Subject: Jforum: Infinite Precision for (some) Irrational Numbers
Infinite Precision for (some) Irrational Numbers
J benefits from the infinite precision of rational numbers. 1/3 = 1r3
Has anyone done any work to extend infinite precision to some irrational
numbers as well (excluding pi but including sqroot 2 )?
Here are a few of my ideas on this topic:
What is a number?
... A number is a vector of integer factors, each with its exponents.
... number =. */ factors ^ exponents
These exponents be they whole or fractional, can be carried through all
arithmetic calculations according to the rules of algebra.
The goal is to obtain almost infinite precision by carrying the irrational
factors through your calculation. We would take advantage of any
opportunities to cancel these factors out, thus eliminating all floating
point rounding errors of irrational and (of course) rational numbers in all
intermediate calculations.
Naturally, some rounding error may creep in at display time, in the final
calculation step, as the one root 2 we have left is finally resolved, but
this can be reduced by the resolution of only those rational numbers that
are necessary to derive the final answer. The benefit is that we have
avoided the intermediate errors, which in some simulation programs can be
considerable.
I would appreciate further comments on this topic, and ideas on what can be
done in J to implement this, if possible.

Why would you want such rounding error "at display time"? If you really
want "exact" arithmetic with irrational roots and so forth, then why not
display the results as such (with either an option to convert all such
displays to decimal form, or a separate primitive to do so).
And why just such things as irrational numbers resulting from fractional
powers? Why not such perfectly good, EXACT, numbers as log (2), sin
(1/2), etc? [To use non-J notation.]
In other words, what is a really justifiable place to stop? Why not go
all the way, at least with purely numerical quantities, to what a
typical "computer algebra system" such as Mathematica or Maple offers?

Toronto, we have a problem!
We are trying to use more recent OCX controls, Farpoint Spread 3 and
Olectra Chart. They both work in J but when closing the form, J bombs.
This is probably attributable to some newer detail in the OCX interface. I
am blocked. My project is blocked.

I have also just managed to start working in j, after many years experience in APL.
My latest contract was capacity planning for a large project conducted by one of our
new combined utilities: a 3-tier NT/ mainframe VB/MTS/SQL*server thing. They have
never heard of APL or j. However, the last time I was doing capacity planning, in
another mixed-machinery environment about 13 years ago, I used APL for both the data
collection & presentation, and also the queue-modelling. So I said I needed j -
quite a risk, as C-P is high profile, & I hadn't used it seriously before! However,
because it was cheap, and I came in as a domain expert, I got what I wanted. I am
currently acquiring fluency (and admiration) for the language & development
environment, having got over the initial distaste for <this> !: <that>. I have so
far been able to (a) catalogue the VB code by analysis of .vbp & .cls files etc, and
(b) directly interface to the NT performance library via some real simple DLL calls.
I'm not sure what the marketing lessons are from this: maybe it's just that the time
to get j into an organization is when the shape of a project is still being
determined. Also (as in the past with APL), when time-pressures are acknowledged -
after a change in personnel, perhaps because the organization's planning function is
in disarray (of course C-P often comes in here, so maybe it's a key kind of
application for j, being Promethean in spanning different machinery and having good
'glueing' properties).

I am currently involved in writing a small, but arithmetically intensive
application requiring sometimes summing columns, and sometimes rows of
non-sparse, large, boolean matrices. I posted this situation on the APL
newsgroup and was told that:
a) there is no boolean representation in J; I should buy lots of RAM, which I
was about to do until I was told that
b) I could use mapped files, which I was bent on trying (despite the slowness
of removing and adding rows to mapped matrices) until I was given the deadline
for the project, so I am accepting the third suggestion that
c) I should post to the J Forum. I am hoping someone here could help be avoid
going down a wrong path.
The problem consists of up to 100 boolean matrices, each of up to 100,000 rows
and about 1000 columns. This is an optimization problem of choosing a small
number of rows from each matrix, such that:
a) when the rows chosen from any one matrix are added to each other, a
specified percentage of the elements of the resulting vector will be greater
than a minimum value.
b) a row chosen for one matrix is disqualified from being chosen for another
matrix.
My reason for doubting the use of mapped files is my feeling that removing
chosen rows would take too long with the copying of files in memory, yet not
removing them would take too long with the unnecessary summing of the elements
of already disqualified rows.
My reason for doubting the use of RAM is my feeling that too much RAM would be
required.
Any direction would be greatly appreciated, even new suggestions. My only
requirement is that the solution, whatever it is, be 100% in J. By the way, if
there is anyone is interested in taking part in this development, I am open to
the idea of delegating.
Thanks.

a. J does have a boolean representation, but it uses one byte per element
rather than the one bit per element in traditional APLs. So your 1e5 by 1e3
matrix would take 100 megabytes.
b. +/ or +/"1 on boolean matrices is very efficient.
c. However you store the matrices, whether in RAM or in mapped files
(or even in APL), it is probably best to work with row indices rather
than actually removing rows. i.e. instead of:
m1=: b#m0
+/m1
do:
j=: b#j
+/j{m0
This way you avoid a lot of data movement (avoid creating copies
or near copies of the original matrix).

An interesting BIG problem made up of lots of little bits!
You are talking about 100 100mb arrays of booleans. J stores a boolean
as a byte. It takes J 8 times as much space to store these arrays as it
would in an APL system with bit booleans. A factor of 8 sometimes makes
a difference, but you have so much data that a factor of 8 doesn't count
for much. The significantly faster performance of J byte arithmetic for
the kind of stuff you are describing will be much more important than
the space.
It is likely that memory management in this problem is significantly
more important than computation time. An algorithm that deletes rows or
columns in its inner loop will kill you. An algorithm that tracks
deleted rows and columns and works that into the computation might do
much better.
If you can avoid the data movement (no deleting of rows and columns)
then mapped files would be a smart choice.
What about storing the data as character or integer to allow 3 states
for each element: deleted/off/on
Regardless, you need lots of ram. A gigabyte would take some pressure
off :)

One of the powerful attractors of APL and J has been the fact
that numbers have been treated as numbers, and one did not
have to get into the internal representation of data. It is
my impression that until recently, these advantages have
transcended the various hardare implementations. For
instance, APL68000 stayed very close to APL2, both on
PCs and on IBM Mainframes.
Sadly, now the J group has made conscious decisions to leave
the Macs behind. I resent this, because of the strong
support I have the J group at the beginning of their efforts.
I have no desire to move to a PC environment, and no desire
to delve up to my elbows into any version of Windows.
I am delighted that Apple has a new lease on life, and
my use of J is constrained by E.Iverson's recent pronouncements.
about LAPACK. I wonder if they would release the source code?
What is so hard about porting this software, anyway?

I build my own computers. This does not save me any money, but I get
the exact configuration I want. Because you want a one-purpose
machine, you may be able to save money with this approach. You can
omit a lot of stuff that comes bundled with a Gateway or a Dell.
OTOH, it's tough to beat their prices. They really leverage volume
purchasing.
I used to buy all my components at computer shows in New Hampshire.
Since I moved to Michigan I no longer have access to computer shows.
So now I must buy from Computer Shopper and the Web.
The core of the computer is the motherboard. For m/bs I like Treasure
Chest, aka TC Computers. Those people really know their m/bs and they
won't let you go wrong. I bought an Asus P2B with a 400 MHz Pentium
II and 256 MB RAM, last November. It cost $992.00. It came with a
video-tape on how to assemble the computer. The URL is
http://www.tccomputers.com/
Since then prices have dropped like a rock. Current prices are:
Asus P2B $137.00
233-450MHz, 1 AGP, 3 ISA, 4 PCI, 3-168 pin DIMMs, Ultra DMA/33, Intel
440BX AGPset, Award, ATX
Intel Pentium II Processor.
333MHz, 512k L2 $144.00
350MHz, 512k L2 $175.00
400MHz, 512k L2 $255.00
450MHz, 512k L2 $419.00
The "sweet spot" in price/performance is the 350 MHz chip. This is
the slowest speed that utilizes a 100 MHz bus.
You can save more money by buying a non-Intel CPU. But the last time
I did the research, the Intel CPUs did the best job of number
crunching. This may no longer be the case.
I also checked out the current cost of memory. The current best price
I've found for 256 MB is a little under $300.
One thing I don't scrimp on is the case/power supply combo. I always
buy these from PC Power & Cooling. The cases are very well thought
out, with lots of nice touches to make it (relatively) easy to
assemble the computer. The documentation is minimal, but that
shouldn't be a problem. The URL is http://www.pcpowercooling.com/
The reason that you might save money with this approach is that
there's a lot of stuff you don't need. For example, you don't need a
CD drive. Just take one out of an existing machine to load Windows,
then put it back. You may not need a monitor, keyboard and mouse.
There's a device you can buy that allows you to flip a switch so that
these devices work with any of several computers. This works for a
multiple PC setup. I don't know if it would work with a mix of a mac
and a PC.
You may want to consider an IDE or parallel Iomega Zip drive. These
are available for $70 to $80. You can download most of the Windows
directory onto one Zip disk. Then if (when) Windows self-destructs,
you can restore without opening up the computer to reinstall the CD
drive.
The downside of this approach is the amount of time it takes. The
guys at the computer shows can assemble a custom computer and install
all the software in about 20 minutes. It takes me days, maybe weeks,
of my spare time.

Hi Brian,
Those are pretty good prices and references.
I've been thinking of upgrading my PII-266 96MB system. I dont know how to get rid of it though !
Do you know if one can run a mixed cpu combo. on a dual cpu board, such as , lets say 266MHz PII and a 350 MHz PII ?
Yes, I realize its more a hardware than a J forum question. Apologies in advance.
Regards,
Max

Subject: Jforum: Plot problem with J for Windows CE
I have been running the Studio/Demos in J402a on
my Velo 500 handheld, which is a Windows CE device
with a MIPS processor. I find that in the "plot"
demo, under "Styles", the the "Point" type only
displays the axes and title, but no data is plotted.
I've run this demo under Win NT, so I know what is
missing. It is not a color problem (the Velo has
has only a 16-level greyscale screen) as setting
pd 'color black' doesn't help. The "Dot" and the
various line types seem OK.
Is this a known problem/bug? It is annoying, since
the 'point' style is the one I would be most likely to
make frequent use of.

Subject: Jforum: Real Part of List Array matrix ?
Content-type: text/plain; charset=us-ascii
Content-Disposition: inline
An array z contains complex numbers.
What is the best/fastest way to get an array of the real parts of z ?
(z++z)%2 works, but because of the division, I question its speed with
floats
and there is the concern of always getting perfect cancellation of the
imaginary
component.
9 o. z also works, but I have no idea what it's doing "inside"
Somewhow I suspect I should be using +. z but attempting to extract
the real part
instead extracts complex elements of the matrix, and it seems that part
extraction would
have to be dependent on the rank of z, never mind the "philosophical"
discomfort
with mixing indexing of complex numbers and vector / matrix indexing.
Many thanks in advance for any assistance.

{.@+. is just fine. In particular, it will return one real for
each complex number. This is what rank is all about, no need for
any discomfort.

You can use a simple benchmark to decide between
9 o. z or {."1@:+. z . Thus:
ts=: 6!:2 , 7!:2@]
z=: j./ _5e4 + ? 2 1e5 $1e5
$z
100000
(9 o. z) -: {."1 @: +. z
1
10 ts '9 o. z'
0.154 2.09805e6
10 ts '{."1 @: +. z'
0.055 3.14746e6
The time/space is small enough that probably other
parts of the computation would dominate.

The code editor colors everything as code. It doesn't know how to
distinguish between between code and text. Neither do I.
This is the simple choice. Any other choice gets complicated and might
just move the problem around. The current rule (everything is code)
allows a line to be colored by itself (it doesn't depend on preceeding
or following lines) and this is a great simplification.
There is a trade off. If you like colored code, you'll have to put up
with some anomolous colored text. If this bothers you too much, turn off
code coloring (or at least ' coloring).
Maybe, as we get more experience with this, improvments will prove
possible.

I'll look at reinstating this. I agree the right mouse menu is pretty
standard. All those standard commands are available with equally
standard keyboard shortcuts. The only one I ever found useful before was
select all, and I now find the ctrl+left margin mouse click to be more
convenient.
The reason it was left out is that I think it will be much more useful
to provide a user defined right mouse menu with your own list of
commands. Until this is done, it might make sense to keep the old
standard.

"Stops Tables"
"Tables d'arr�ts"
The current rule (everything is code)
allows a line to be colored by itself (it doesn't depend on preceeding
or following lines) and this is a great simplification.
I agree to make it simple. Since you don't color strings between double
quotes, then don't color anything between a single quote and a double. Just
color strings between single quotes. That way, both lines at the beginning
of this message would be uncolored.
No trade off.

As you may well know then Debug is a special favorite for me in this
beta.
The first impression is that it looks very promising and you are on the right track.
I managed to get a strange behaviour in the last steps of the lab when I
was in step 24
dbstop 'pqr'
pqr 7
143
628
Because I had not gone out of the example in step 23. It was still active
so executing pqr 7 I should have been getting monadic but I got dyadic
in the debug window.
The colouring also looks promising
It is about time to get back into active J mode. I have been neglacting J quite
a bit I am afraid these last few months.
Thanks for this Beta.
I am looking forward to several weeks of interesting testing.

In J the " character is a primitive (rank). It is not a quote type
character. Since the line is code, the " is a primitive.

Where to reset its default value of 1 to another? The scripts display is

Why complicate the two finger stroke ctrl-arrow? It is one of the most
common actions: adjusting the last statement you just did. Now it is three
fingers. More complicated. More effort. Why do this? You should ask first
before doing this. I use ctrl-arrow hundreds of times a day.

are no guarantees

I completely agree. I wrote the WorkBench because
I considered even the Ctrl-Ups to be too much hassle.
The WorkBench keeps the phrase under development in place. Hitting the
Return key triggers evaluation, but the cursor stays in the phrase at
its position.
The WorkBench keeps also track of the test parameters without tying
them into the phrase definition.
The recent changes in the WorkBench guarantee that it will be able to
run without a single line change. The only thing you have to do is to
drop the CVS module formally referenced as
:pserver:anoncvs@juggle.gaertner.de:/j-contrib-w
into your Windows J directory.

Others have complained of this as well. I now see it was a mistake and
will reenable tab. I'll put up a new beta with this and a few other
changes late today.

The beta is a beta and that means the risks are unknown. However, I
think it is quite stable and don't expect serious problems with the core
engine as most changes were in the GUI. You could move your development
to the beta with caution. Obviously you can't distribute anything with
the beta. The beta expires at the end of this month. The release will be
before the end of the month.

Providing the beta is an effective way of asking.
Almost all other editors use ctrl+up/down arrow to scroll the view. I
decided that following this standard was fairly important. This meant
that line recall had to be something different, and I chose
ctrl+shift+up/down. I still think this was the right choice. Give it a
little more chance.

People here are keyboard people. They use more often the keyboard rather
than the mouse. They never use ctrl-uparrow to scroll. They page up and
down. THe command may be everywhere, theoretically. Do we want to be
compatible with an unused standard or make it easier for the human users?

Content-type: text/plain; charset=us-ascii

As long as we seem to be tinkering with the user interface -
On a high res screens eg 1600x1200 or XGA Laptop, the default ISIJ font is
not very legible at small sizes, especially given the crucial role played
by puctuation characters in J, so I usually need to expand them to 12
points, reducing the amount of code I can view simultaneously in a window.
Standard Windows fonts such as Terminal or even Lucida are much more
legible at very small sizes, but of course lack the linedrawing chars.
If feasible, I would suggest an alternative J font based on Terminal, or
Lucida, if it needs to be TrueType.
Many thanks.

We are not talking about the mouse.
A window editor standard is that ctrl+up/down arrow keys scroll the view
by one line. This is quite useful and I find that I use it quite a bit.
Try it, you'll like it. This is more useful in ijs windows than in ijx.
The ctrl+shift+up/down is not a difficult key combination. What is
difficult is the transition, especially while using both the old and
new. I think you'll get used to the new way pretty quickly.

the script -> HTML publisher is very nice, but wouldn't it be better to do
the formating with style sheets? for a one off display with embedded styles,
but for publishing+keeping using a global style sheet file (ijs.css?) which
makes it easy to keep the format of all published source files synchronised?

The wheel on a Microsoft Intellimouse (with current drivers, under
Windows 98) works ALREADY with J 4.02 to scroll in both session manager
window and in editor windows!
At least it works in the following respect: rolling it up or down
scrolls the currently active window accordingly.
What does NOT currently (in J 4.02) work is the "automatic" smooth
scrolling such as in Intellimouse-enabled applications like Microsoft
Word 97: click the mouse wheel, then move the mouse, say down; the
window contents automatically scroll, and the scrolling speed can be
increased or decreased by moving the mouse further down or back up.

I second the font suggestion. The font that is still readable at the smallest

Hi Jake
Old timers on this list are probably mostly using Norman
Drinkwaters suggestion, Monotype.com, as their font.
Monotype is available at:
http://www.microsoft.com/typography/fontpack
Perhaps someone should negotiate to get this bundled
with the J distribution? However Chris said back in
October that it might be difficult to licence and
suggested a note in the documentation. A quick look,
using Find in Help, did not show a reference to it
though...

Yes, this is a nice feature of the new editor.
On any line:
press home once - moves to the beginning of the entered statment
press home twice - moves to the beginning of the line.

Your second wish is already granted. Home moves to the first
non-blank/non-tab character. When I put up a new beta version tonight
with tabs back at 4, you should have want you want in this area.
The first part of your request (auto indent after enter) is a bit
trickier. I'd need to think about it before including it in a beta. I
don't think it will make it into this release. It could in the next. I
must admit I like that feature when coding in other languages.

The only registry entries J makes that are of any importance are the
registry entries for the COM JEXEServer and JDLLServer. These are
important only if you run applications that use J as an Automation
server. Any J install updates those entries to point at the new install.
You would have to use jreg.exe in another installation directory to
reset the pointers there.

Chris pointed out that you can color the NAME to the left of a =: and =.
differently. In addition, you could use either as a keyword and color
the =: or =. primitive differently. There is a lot of stuff to play with
in the color dialog!
Perhaps Anne will eventually want to post a prize for the best and worst
submitted color schemes. I'm not sure what first prize would be, but
second would be perpetual beta testing.

I, for one, would prefer not to have auto-indent. When I have worked in various
dialects of BASIC I have found it to be a nuisance as often as it has been a help.
If the consensus is to have it implemented, perhaps you could give us the ability to
turn it off in edit/configure.

A second version of the J 4.03 beta is now available (NT/Win9?).
http://www.interlog.com/~eiverson/j403a.exe
This has a few minor fixes: tabs; ctrl+shift+F2 clears marks; debug
interactions with other forms (e.g., pousse).
Download, install, start J, and read the Release Notes (Help|Release
Notes).
Please send comments and problem reports to this forum.

I second the suggestions of others that the editor:
(1) automatically indent to the same level as the preceding line;
(2) allow configuration for variable tab widths.
I expect these features in programming editors.

Could be a question of how recent your Intellimouse driver is. I tried
to find out the version I'm using (which I had downloaded from the MS
site long after buying the mouse), but I haven't a clue where under
Windows 98 to find that information!

I'm not sure I see why auto-indent (upon Enter after an indented line)
would be a nuisance:
Why would you be indenting a line of code but in order to indent a
(large or small) multi-line block within, say, an if. ... do. ... end.
clause? At the end of the indented block, a single Backspace/Tab would
remove the indent from the next line. That's just one "extra" keyboard
step per indented block; without automatic indentation, it takes an
extra keystroke of Tab for EVERY line in the block.

Chris,
What about an idea to run wdiview on name that is doubleclicked? I put
cursor on a name in session, doubleclick (or shift enter) and J reads the
name and opens wdview if the noun or verb is defined.

I, too, expect these features in a general purpose editor.
However, for a code editor that is integrated into the interpreter,
there is the opportunity for all that and more.
For an example of something of this class, I would like to draw your
attention to ALICE: The Personal Pascal from Looking Glass Software.
This product includes a syntax-directed program editor. In this
language it is impossible to create a program that has a syntax error!
ALICE: The Personal Pascal was introduced in 1986.
The syntax-directed program editor was inspired by the Cornell Program
Synthesizer from Cornell University. The work of Mark Horton of
University of California of Berkeley is germaine.
Studies at Berkley indicate that students learning in this environment
learn the syntax equally well. It is just easier.

I wanted to keep the first version as simple as possible, and wasn't sure how
I could map the more general formatting by verb definition onto style sheets.
Note that, if you produce your own .css, I believe you can use the verb
definitions of a scheme to produce html which references it. I'll try to
come up with a simple example of this and post it to the forum.

Thanks for the bug report (coloring name to left of =: incorrectly
colors =. and coloring name to left of =. has no effect). I'll get this

Doubleclick is already defined to select the word. If a rightclick
displayed a menu (user customizable), you could have a menu command that
was wdview of name at the caret.

You can use configure|color to color the naked paren that closes

There seems to be a problem with the Project Manager in
J403 beta. In the Build Options dialog box in previous
versions (at least 4.02a) there are references to both
"Target" file and "Build" file. These references are missing
from the 4.03 beta version.
Is this an error? If not, then how is the new version to be used?
Please note that the corresponding Lab in 4.03 assumes no
change from the prior version!
Oh ... I forgot ... I mean 4.03 Windows (NT/9?) version.

I was trying to be modest in my request.
But yes, syntax-directed editors are MUCH easier to use. For a start:
(1) Facility to actively match parentheses (not just differently color
an unmatched one).
[Yes, I do have need for parentheses in J -- especially when I
dislike coercing
a phrase into a parentheses-free version by, say, using Passive
(~).]
(2) Likewise, matching single quotes on strings. Ideally, matching
double quotes
on string-like expressions that are increasingly needed in arguments
to wd and
openGL commands. [Interesting developer challenge, perhaps, given
use of " for rank?]
(3) Catching missing do.'s, etc., in keyword clauses within explicit
definitions.
Yeah, the interpreter catches such things AFTER the definition is
complete. But for real efficiency, having them caught before is much
better.

I don't like the new grey-banded left margin indicator, even though it

Any clues as to what you were doing before this?
Can you reproduce it?
Are you using the latest J403a beta?

Importance: Normal
I type in my indents by hand because it always reminds me of
the scope of the assignments I have made, and keeps my constantly
thinking about the nesting structure. I prevent a lot of bugs
this way.
With J it's not as important as with C, but life is too short
to spend it changing habits that work.
I agree that finding the matching parentheses and quotes would be great.

Please give more context in your report. If I start J and do this I
don't get an error. Do you? If not, what are the simplest prerequisite

Use configure/color to change the color of the left margin.

On a related topic to auto-indenting, I use the pretty print facility
in Project Manager all the time. It indents for me, so I can enter
code any old how. It also checks that control words are matched up.
Ideally, something like this would be done immediately in the code
editor - but probably not for this release.

I hate such auto-extensions. Depending on the context, I'd be needing
an .html, .htm, .HTM extension or even none at all. It always bugs me
when I want to create a simple "README" file using notepad and I end up
with a README.txt.
The J session manager used to have some forced filename extensions in
some earlier version and I'm glad they are gone. (It meant that you
couldn't write a README file using J, either.)

Subject: Re: Jforum: j 4.03 code editor
I used ALICE (the syntax directed Pascal system) for some time
when I went through my "SDE is hip" phase in the 80ies. My overall
experience was that navigating around/along the syntactic structures
is often needlessly cumbersome. Brad Templeton's experience in turn
was also a small surprise. His conclusion was: an SDE is the best
way to sink work and money into a dead project right from the start.
(At least I was suprised when I got these words from him, since I also
considered ALICE to be a very well done product in its own respect.)
Around that time I also had loads of nifty vi editor macros for
creating C templates, and later I used emacs with its electric
language modes. Two years ago I returned to comparatively simple
editing with vi. My lesson is that for any electric convenience
feature, there are equally many occasions were it becomes a pain
somewhere to disable them temporarily or undo their unwanted effects.
I know that personal preferences vary wildly in this respect.

Of course if you in fact Save As "README" (with the quotation symbols),
it won't tack on the .TXT extension (at least not in NT Notepad).

That made me expect that the extension will be added.

<div class="jcomment">NB. this is a comment</div>
<div class="jname">avg</div><div class="jlocalassignment">=.</div> ..etc

just remembered the html editor html-kit (at

that it has the option to take an html file complete with <font color=..>

I tried to run the J 4.02 NT/95 lab grid example:
corequire 'jwatch'
d1=: ?1+i.7 15
w1=: 'd1' conew 'jwatch'
I am having a problem when I try to edit the cells. It will take single

the message "Error."
Has anybody else experienced the same problem?

Wow! that is a great tip! i have been frustrated by that
particular bit of Fascism for a long time.
Still the better way to design it is to put a default in -
but let it be overridden easily. Eg if the default is
.html, it should be easy to just delete the last "l" to get
the three letter .htm. And not have the system come back
with .htm.html!

The J install (unzip of files to J directory and setup) has nothing to
do with MS Outlook Active Setup. I asume/hope something completely
unrelated to J did this to you. Please check further and let me know
what you find.

I don't have much time to test these days but I liked very much what I
saw.
One little thing, the OpenGL demo, once active, does not recognize a
change
in the color settings from the properties of my desktop. It actually
displays errors
all the time from that point on. (Found that by accident). I suppose
it's one of those
Microsoft limits or something... I am using NT 4.0 patch level 4
I am really impatient to have some more time to test...

I think it's related to J... here's what I do:
1. Windows Explorer, go to 'Internet Temp', double-click 'j403a.exe'
2. WinZip Self-Extractor comes up, I click 'OK'
3. J 4.03a Unzip comes up. I set directory to e:\Jbeta, click 'Unzip'
4. files get copied, I get WinZip Self-Extractor message
'687 file(s) unzipped successfully' - I click 'OK'
5. J 4.03a Unzip and WinZip Self-Extractor go away, and up
pops 'Outlook 98 Active Setup'.
This is easily repeatable. I run Microsoft Outlook as my normal
mailer, and in fact it was running while I ran the extract.
So, I just closed Outlook, repeated the extract, and it still
happens.
Any thing else you want me to try, let me know.

You can do much of this by editing the scheme and using verb definitions,
eg: hit Edit and select "name" in the Elements listbox. Select "by verb
definition" and supply the verb: DIV class 'jname'
This verb wraps <DIV class="jname">...</DIV> around all J names.
I find both IE and Netscape add line breaks at the DIV tags.. is this your
experience too?

Emne: Jforum: Plot problem with J for Windows CE
I have been running the Studio/Demos in J402a on
my Velo 500 handheld, which is a Windows CE device
with a MIPS processor. I find that in the "plot"
demo, under "Styles", the the "Point" type only
displays the axes and title, but no data is plotted.
I've run this demo under Win NT, so I know what is
missing. It is not a color problem (the Velo has
has only a 16-level greyscale screen) as setting
pd 'color black' doesn't help. The "Dot" and the
various line types seem OK.
Is this a known problem/bug? It is annoying, since
the 'point' style is the one I would be most likely to
make frequent use of.

This has always been the limit. The current symbol table architecture
requires a fixed value and we wanted to keep it small so that the memory
footprint of a locale for an object was small. It has always amazed me
that users hardly ever hit the limit. Perhaps a consequence of an array
language with locales.
We have specs for a new symbol table architecture that will be even
smaller and has better performance, yet easily grows to any size.
Unfortunately we have not yet impletmented. It is on the serious wish
list.

I have lots more than 240 names in my _z_ and base locales. Are these
locales special? Or are verbs in a separate table (most of the names
are verbs)?

File status.txt in the help directory lists a few limits. But not this
one. We'll try to be better at documenting this stuff. We'll also keep
working on removing limits (and then removing the earlier
documentation).

I should have made it clear that there are 2 limits:
limit 2028 symbols in named locale
limit 240 symbols in object (numbered) locale

There are always a lot of limits in software applications. Some are
platform dependent and some are because of the application design. The
designer has to make a lot of compromises between limitations and performance.
Yes, we need allways better documentation but more we need discussion if
there is a relevant need to remove any limitation. If one limitation
bothers only you can you change your algrorithm?

This reminds me of a minor problem: The Configuration menu does not have
any "Restore defaults" button. I would like one -- if not on each tab
of the configuration, at least for the entire configuration.
Yes, I know, I SHOULD have made a backup copy of the distributed
config.ijs, etc., but I didn't. (And someone new to J might find
herself in the same situation.)

Please don't "help" (or force like Microsoft VB does) us format in the particular
style of prettyprint. I happen to disagree with some of the indentions that
prettyprint does, but make no difference in the execution. I don't have to use
prettyprint if I don't want to, but if automatic formatting is in the editor and
can't be turned off, then I'm stuck.
I developed an indention convention from SPF. I really liked the ability to see
structure where everything within a block is indented more than the beginning
construct and the ending construct. This makes it really easy to match up
beginnings and ends of blocks. Take the select. I like:
select. ...
case. ...
case. ...
end.
But prettyprint puts the cases indented to the same level as the select and the
end. Which is better? Who knows. I guess it doesn't matter very much as J has
such small blocks, unlike PLI. But don't act like Microsoft and tell me how I'm
supposed to indent.
Enough griping. Now that this forum is making editor wish lists, how about the
exclude line facility of SPF? It is very useful pulling together sections of code
which ordinally can't be seen in the same window at the same time.

Yes, I see the source of my confusion now.
Indeed, inside J, every font I specify displays fine with oem set.
It's when I copy from the J window and paste into Microsoft Word
(for note-keeping) that the text must be formatted ISIJ in order to
see the boxes.
This situation is actually quite tolerable. However, it would still
be of interest to know whether there happen to be any other fonts
which map the same line-drawing chars as well as ISIJ, but with
more readble roman chars.
Monotype.com has evidently been renamed Andale Mono, and that seems
to map the same as the generic Windows fonts.
Thanks
Jake.

There was some discussion about J installation & Outlook interference. Here
is my experiense that might help.
I am using EudoraPro 4.1 and Win95. Eudora is loaded and minimized. Every
60 minutes it automatically checks my mail.
While I am working with J with session maximised and PM in background
Eudora starts its hourly operation, suddenly PM becomes visible without I
do anything. The same happened also recently with wdview windows.
So I confirm that J somehow interacts with applications that are related to
e-mail or internet. Is it possible that there is a Windows system naming
conflict or something?

Right now, you can only define a function key with a statement that is
executed.
However, you can do what you want by defining a verb that writes to
the session, and then put that verb on the function key.
In your example, you use the following definition:
foo=: wd bind 'smprompt *wdview ":'
You could also read (smread), edit and write (smwrite) the session as
a whole.

The point plot depends on the size of the symbol font. It should not,
and this will be changed in the next release.
A quick fix is to define a bigger symbol font. Try adding to your
program:
pd 'symbolfont tahoma 100'
or make a similar modification to script:
system\classes\plot\plotdefs.ijs.

In general we don't find one of these in isolation to be very useful.
What we really like is a set of steps to reproduce the crash.
If you are having quite a few crashes, then email any info that might be
relevant along with a few of the crash logs.

General questions about creating animated plots:
(1) Is there a way to build up a series of J plots into an animation,
either AVI, MPEG, or QuickTime ?
It can be done in MathCAD, but can take days to generate less than
a minute of video.
(2) Odd (to me) observation: It seems quicker to calculate on the fly
than to pre-compute massive arrays and then spit them out row-by-row.
(3) Anyone care to point out better/faster techniques than I'm using
now ? plot is no faster nor slower than pd, as far as I can determine.
What about using OpenGL ? GnuPlot ?
MovePd =: 3 : 0

Use the "OEM" rather than the "Ansi" or "Default" setting in Edit|Config.
(eg, this gives you the font: "Andale Mono" 16 oem )

I am not sure I understand you correctly.
I think you mean that it is quicker to work with
small number of data in verbs called over and over
again rather than creating big matrixes.
If your matrixes get really big so that the real
memory of your machine can not handle it then the
operating system will begin to use paging and swap
virtual memory in and out of real memory.
That might explain your observation.
On the other hand if you would increase real memory
to be big enough, I am pretty sure your observation
would be the other way. Also depending on the methods
you use of course.

My experience is that big arrays require memory allocation etc. that makes
them sometimes slow in RAM too. It depends on the operation and data type.
I have now some experience with j mapped files and there I can store big
arrays (28MB) and make operations real fast. My solution is to preprocess
data into a 4 dimensional big array sotred in a memory mapped file (jmf).
The reporting then scans this array very fast using basic J expressions
(...+/"2 jdata)(...+//."3 jdata)(1{23{2{jdata)(...#"3 jdata) etc..

I understand now. After a change of the color settings, say from
16-bit to 32-bit color, OpenGL crashes. I dont think this is a J
problem.
In Win98, changing color settings gives me the following warning,
which I guess applies here:
"The settings you have chosen may cause some programs to operate
improperly if you do not restart your computer now".

In stdlib, I use the clearall verb to clear out all the remnants of a previous debug

There is still a comment in this library, but no "clearall" verb.

This is a bug - the grid edit is reading characters in unicode,
instead of ascii. Here is a workaround:
1. Remove ascii 0 from the input by modifying seteditdata in
system\classes\grid\jwgrid.ijs to change
data=. ". data
into
data=. ". data -. {.a.
2. On input, enter as many trailing blanks as numbers, e.g. for "123"
enter "123 ".

clearall was in J3 stdlib. I'm not sure why it was taken out for J401.
clearall was in effect:
clear each nl 6
After this, you probably need to read in the standard profile:
0!:0 <'system\extras\config\profile.ijs'

From: "Piet de Jong" <piet.dejong@commerce.ubc.ca>
X-Fontfamily: Geneva
X-Fontsize: 12
Content-Transfer-Encoding: quoted-printable
With all the excitement of the J403 release on Windows, here is
something for Mac fans, just so that they don't feel left out.
I have G3 Mac with a 2 year old version of RealPC installed on it.
This is a pretty basic and cheap Dos emulator. Inside RealPC I
installed Windows95. Kept the installation to a minimum, no internet
etc. Then I downloaded J403beta using my Mac browser and dragged it
to the appropriate directory in Windows95. Unzipped, installed and
started things. J403beta demanded an updated version of one of the
- .dll files (apparently my Win95 was old). Located and downloaded
this from the web. Then J403beta demanded another updated *.dll file.
Got this one too. Then J403beta fired up without a hitch.
Installed LAPACK without any bother and everything appears to run
smooth.
One glitch -- File|Open doesn't work. Windows reports an error and
closes down the program. However pulling in a previously worked on
file listed at the bottom of the File menu works fine. Graphics etc
etc appears to work just fine. LAPACK works great.
The interface seems slightly sluggish compared to running J3 on a Mac.
But here is the interesting part.
J403beta on Win95 on RealPC on MacOS8.5 on a G3
runs about 5x FASTER!!! then
J3x on MacOS8.5 on G3
I find this hard to believe. Maybe it has something do with the
number of programs running, who has the priority etc. For example
10 (6!:2) '%.?100 100$300'
1.96 NB. J403beta on Win95 on RealPC
on Mac8.5 on G3
9.5 NB. J3x for Mac on G3
10 t'128!:0 ?100 100$300'
1.15 NB. J403beta on Win95 on RealPC on
Mac85. on G3
5.1 NB. J3x for Mac on G3
0.55 NB. J403beta .. on G3 with LAPACK
qr transform
Some other cursory timings indicated that J3 on G3 was faster by a
factor of 2. So relative performance appears to vary with a number of
factors.
The bottom line is that it appears that running J403 on a Windows
emulator on a Mac is quite respectible. Okay, maybe no weather
simulations etc, but unless I hear otherwise, as a commited Mac and J
person, this will be my upgrade path.

I am trying to connect to an Oracle v8 database and can't seem to get
the
connection parameters right.
ddecon'dsn=oracle8;uid=mine;pwd=secret'
always gives me the following:
IM002 0 [Microsoft][Gestionnaire de pilotes ODBC] Source de donn�es non
trouv�e et nom de pilote non sp�cifi�
On the other hand, ddecon'dsn=oracle8'
gives me the following:
28000 1017 [Oracle][ODBC][Ora]ORA-01017: nom d'utilisateur/mot de passe
invalide; connexion refus�e
Which was to be expected.
We also use that database with APL-Link and they seem to go through a
"console"
which is the first parameter (before the dsn) that we pass to their
function. So my
question is: What special wizardry in the syntax (or missing console)
should I do
in order to at least connect to the "thing"
P.S.: Sorry for the french error messages but NT 4 SP 4 is in french
here.

From: "Piet de Jong" <commerce.ubc.ca!piet.dejong>
J403beta on Win95 on RealPC on MacOS8.5 on a G3
runs about 5x FASTER!!! then
J3x on MacOS8.5 on G3
I find this hard to believe. Maybe it has something do with the
number of programs running, who has the priority etc. For example
10 (6!:2) '%.?100 100$300'
1.96 NB. J403beta on Win95 on RealPC
on Mac8.5 on G3
9.5 NB. J3x for Mac on G3
I find it hard to believe as well... I was always (very) disappointed
with J performance on my Mac, but when I installed 4.02A I sent a note
(1999 Feb 18) apologizing for all my grousing in the past and included
the following (also, I should note that the OS was 8.5):
-----
I could use my Mac in lieu of the Sun SPARC station that I have used
in the past (although it still has it's attractions) to do large
processes. The Mac is satisfyingly fast (this is a radical improvement
now that J is compiled to be Power PC native). Here are some
benchmarks from various platforms:
266 MHz Mac G3
timex =. 6!:2
5 timex '%. ?100 100 $1000'
0.7568
333 MHz Pentium - Linux
5 timex '%. ?100 100 $ 1000'
0.247367
UltraSPARC 2 ...
5 timex '%. ?100 100 $ 1000'
1.06708
The SPARC has a great I/O system - but the others are OK too. The
SPARC is about 5 years old, so is a bit "long in the tooth" for
raw computing power... Still, it compares (more than) favorably
with the last time I used a large IBM mainframe - amazing!
----
Your note caught my eye because you used "my benchmark" as a test -
actually, back in the old days of small/slow IBM 3090s (!!) I used
a 50 50 matrix. To confess even more, this goes back to the even
(much) smaller/slower IBM/360 model 50 where I first had a
"personal" APL system (circa 1971) 100 by 100 was too much to
ask of those machines.
When J came along, I forwarded some timings to Roger Hui with
an apology for using something so narrow as a matrix inverse and
was surprised by his response that %.? was a rather good general
benchmark for computations in J since the algorithm for %. was
essentially "written in J" and therefore used almost every part
of the system (unlike the 360 code where it was a special module
written in 360 assembler language...)
So, I think you have some other factors involved in your timings.

In fact, MS Word supports box drawing chars for Unicode fonts,
e.g. Courier New has such chars, which look quite tolerable
at small screen sizes. However the procedure to make Word
convert to proper encoding when pasting or importing is
not trivial. I used to do it with modifying the RTF output
of WordPad and then open in Word.
Earlier in the thread Windows Terminal font was mentioned.
Indeed, it has box drawing chars as any other OEM font should
(unlike e.g. Fixesys). However, very few programs are able
to display it at a size, in which it appears in MS-DOS Command
Prompt box. Under Win31 it was a nice alternative.
The attached picture shows its ability to draw symbols very
briskly for good readability.

Subject: Jforum: Extra characters in session (J4.03)
In-Reply-To: <199905171349.GAA24636@locus.qued.com>
There are some problems in J session manager. I use a lot ctrl-R to run
functions line by line. Now I have experienced several times with J4.03
that there are extra characters. Here is an example from my current session:
The line in ijs-windows is:
selrows=. ((1 col weightrows) e. i{sellers)#weightrows
But pressing ctrl-R I get to ijx-window
|syntax error
| selrows=.((1 col weightrows)e.i{sellers) #weightrows==
Where comes the == to the end of the line? The same error exist in several
lines with different extra characters. It does not help to close and open
the ijs-window.

But the Oracle Tool SQL*Plus does not even look and feel
like shareware. It looks and feels like a novice programmers
first experiment. (There's power behind the screens
nonetheless, too.)

The timings sound wrong. Is it possible you are running the 68000
version of J instead of the PPC version? That would explain your
numbers.

I don't think I could say that a product looked like a shareware product

Can you be more specific as to what made them come away with this
impression?
Did you, for example:
- run one of the supplied demos (e.g., graphics)
- quickly build a form
- with a bit of typing (or, from a previously programmed form) calculate
statistics from a data set in a file?
My experience is that that sort of thing will grab the neophytes --
provided it doesn't intimidate them!

My experience is related to a longer working session, PM, Form editor. Also
this is related to debugging code (however I do not use the debug facility,
just go through code step by step with ctr-R).

Hello Murray !
Yes, I did all of those, I ran the OpenGL demo then quickly built a form
then showed them a few statictics in the J session window.
My beleif is that since there was a lot of negative vibs from earlier
APLers here, a reputation and negativity before you even say anything is
persisting.
On the bright side however, I just increased the performance of a
section of their code (APL2000 based) by a factor of 20:1 also using
less space in a ratio of 6:1 within a few days and frankly it annoyed
them because now I am moving from a "he is another APLer !" to "how much
faster did he make it run ?".
I will eventually move towards a J development environment but it will
take some time... They also made the comment "why are there people
trying to revive an old and dead language like APL". I am upfront with
them and I don't try to show J as a non-APL or it's not called APL or
whatever else one can imagine. I also give proper credit to Kenneth E.
Iverson and all the people surrounding current and past development of
the concepts behind J. Therefore I am stretching the schedule a bit more
but I also keep my integrity and a clear mind (as much as I can).
They are also very young people with a strong interest in putting
"maketable skills" on their CVs and I heard that more than once
before... They lack depth and are in a hurry to get things done with
little regards for anything else but fun so their fast judgement should
not be a yardstick for all neophytes but rather be a fact of life to be
delt with.
The real circumstances that led to my posting is that they now know that
there is a J community out there and that those "crazy people" exist. In
the near future I hope to prepare better ground for some of those "crazy
Jers" to come down here and expose a few things. So the posting is
really a reality check as well as a message saying something like: OK
you have views about J so let's share them with others and see what they
have to say. So far so good, the responses from the forum are red back
to them so that they now know a bit more about other's opinions and to
me it opens up options.
So whish me good for I will need to exercise patience (a quality I had
only for coding before) in order to generate a stimulating J group here.
I was (still is...) a pretty square person about APL/J/K in the past and
I am trying my best shot to learn something from all those frustrating
past experiences in order to make the current one better for everybody.
Thank's for your interest.
Regards/Paul

I think I understand what they mean. And I hope we take it seriously:
now that I'm pretty much a full-time J programmer, I sure don't want
to have to change, and that means ISI needs customers!
Bring up Microsoft Visual C++, then bring up J: what differences do you
see? (I am using J4.01)
1. While Visual C++ is loading, you get a pretty picture with your
licensing information. With J, you get nothing (because it loads too
fast).
2. Visual C++ starts you out with a Tip of the Day (I haven't even used
C on my machine enough to turn this off, thank goodness!). J has no such
gadget.
3. Visual C++ has pretty-pictured buttons on the toolbar. It also has
the same pretty pictures in the menu. Help bubbles pop up if you linger
over screen areas. J has no toolbar, and the menus are in a single font.
4. Visual C presents you with several panes to type into, and several
listboxes that let you select what-I-don't-know, and neat shadows and
tastefully-drawn lines that set off the various components. It fairly
bristles with latent power and sophistication. The J Session Manager
comes up looking like a DOS 3.1 screen, functional but plain.
5. Neither system has sound effects, a glaring flaw in Visual C++ I think.
(I have just violated my personal rule against sarcasm on the Net,
but I hope I'm among friends).
So, yeah, it DOES look like shareware. This is no problem for me, but
if something turns potential users off, I hate it. And I wouldn't want
ISI to stop what they're doing to add pretty buttons.
I don't know how to make J appeal to the MTV generation on a first
encounter,
but I bet it involves glitzy applications, and I bet that it's the J user
community that will have to assemble them.

I assume you mean this forum. I am not sure what you
are refering to. I have seen many things about
programming Linux. What is basically missing in J for
Linux is an X interface as far as I am concerned.
Once X is in there will be a lot of interest in J for Linux.

My own experiences as (1) neophyte, (2) enthusiastic proselytiser (?) and
(3) senior customer dealing with various suppliers is this:
As a neophyte, I have become enthusiastic about 'new technology' at various
times: it has always been an uphill struggle to convert my seniors to
anything, and any product which has been most successfully 'sold' at the
lower levels of an organization has actively suffered from a geek image
problem. The products which sweep markets are in fact sold at a very high
level, on grounds which would leave techies open-mouthed. I remember the way
IBM hardware penetrated BT in the UK in the '70s in the face of technical
superiority of other providers by a strategy of talking only to very senior
people.
The principle surely should be to convince customers at exec level, and let
them worry about telling their troops the good news... I also seem to
remember that for several years APL rode in at IPSA on the coat-tails of
quite mundane corporate needs for large quantities of globally shared
private or public data.
As a principle customer (ie with buying power), I found my buying decisions
were dominated by specific board requirements for, say, stability in the
face of competition, or growth or cost targets. I would have felt vulnerable
appearing to be led by my juniors, so even if I were inclined to adopt some
software on technical grounds, I would probably cloak that decision-basis in
non-IT terms. I am sure this is the way hundreds of copies of software get
bought, as opposed to the odd one or two.

I am sending a translation of a french message I received this morning.
I don't know if it's true but weighting the odds I decided to follow
suite and I therefore send it to this forum hoping not to be misled.
Maybe I am naive but I am willing to take that risk. So, here it is:
Jessica is a little 7 years old girl having a brain tumor which can't be
cured. Doctors give her 6 months ti live and her last wish is to start a
worldwide chain of E-Mail to inform people of her state. She wishes
happiness for their whole life to healthy people and moreover that they
learn to appreciate life before it is too late.
The American Cancer Society receives, for each E-Mail sent to their
address a gift of 0.03 USD for research. Please send this E-Mail to this
address :<mailto:ACS@aol.com> and send copies to everyone you know. This
is a gesture that cost you nothing but nevertheless can do much.
Thank you.

The item does not say who is paying the 0.03 USD, and my impression is
that the address might be wrong. The American Cancer Society has
their own site, "cancer.org".
If this is not the official e-mail address of the society, then
why send mail there? It could be a way of collecting e-mail addresses,
or it could be a way to flood someone elses mailbox.

I should admit that I am a naive never cloaking anything person and I
used to have difficulties with that but now I deal with it for what it
is... Straight sincere naive honesty. I know it's not politically
correct for most complex paradigms in society but life to me has pointed
very clearly that one of the main source of suffering is lying and/or
cloaking. I might be an extreme in that sense, but it's me.
So I am glad that people like you can deal with the political side of
things because, I could not, in the next hundred years... It makes both
my charm and my drawbacks.

I have a sister actually dying of cancer and my heart was faster than my

I suppose, "tip of the day" feature should be included in j startup

Subject: Jforum: Selling/introducing J/APL
Once upon a time, I managed to make APL the main development language in a
rapidly growing (at the time) computer sales and manufacturing co. We ended
up essentially running the whole $2B subsidiary on some 12,000 lines of
code, building applications from tools implemented in APL. The reason it
succeeded was that I was supported/protected for a few months by a senior VP
of finance, long enough to deliver the first results. The reason for the
support was the ability to deliver fast new development and problem
solutions otherwise unavailable. Senior management did not care about the
language, they only cared about results, and that they got. They also got
reduced costs for IT and the benefit of common data from dictionary driven
tools.
The opposition was all from the lower levels. APL did nothing for the
resume. It reduced the number of people needed and hence the size of the
department. Not all of them could adjust their thinking to become
effective. The manager with an approved 18 month budget for 30 people was
not happy to find out 3 of them with our tools could do the job in a few
months. He told them to go back to COBOL and forget what they had learned.
Programmers threatend to transfer out of IT departments if the manager
adopted our tools. Despite all this our techniques were used at several
other sites around the world where the adopting group was under sufficient
time and budget pressures. Neither the developers nor the users saw any APL
as such, they used tools, automatically generated forms and query techniques
that happend to be written in APL.
J runs into the same support/opposition issues so long as it is a niche
player. The programmers don't see any advertisements for J experts but
hundreds for Oracle, C++, Java, SQL, and so on. Their managers don't get
the warm and fuzzies from expensive national advertising that validates
their choices. Talking about a J development environment with fellow
managers is a non starter. Adding J to the resume does not get you the next
bigger job.
So accept it. Just use it. Preferably not to build applications directly
in J, but to build generic tools for applications development. Solve the
problems better and faster than others. The business managers will back you
and once you are the CIO ...
As a last note, I remember a COBOL programmer's put down of "Apl is all very
well if you need a fast solution". To which I asked "has anyone ever asked
you for a slow solution?"

Subject: Jforum: Closing Functions
Date: Wed, 19 May 1999 10:07:06 -0700
I have had an ongoing battle with the closing bracket " ) " on functions and
hope somebody can give me a clue as to what is going on.
Sometimes, not often, I will get an error message that looks like this
�ill-formed number
� fill=: 3 :0
�[-38]
The [38] is pointing to the " ) "
Usually the function is the last one in the script.
When I look at the list of names, that function is missing.
It often happens after some editing and usually when the function has been
already running.
Sometimes when I move the function up in the script the problem cures
itself, not always.
I am running Win'95 with ver 4.02a
Any ideas ?

I find it difficult to respond without a rather exact sample of the
code that actually caused the error..
Offhand I'd assume you had an `ill-formed number' in your text and
that this was causing the problem not the `)', but without the
sample it is difficult to tell...

I think this "phrase of the day" suggestion is a great idea. Probably
too late for the 403a release, though.

Even with CIO backing success is not guaranteed. K had backing at that

I believe the best niche for fringe languages like APL (et al.) is in
small service companies that write and use their own tools, not in the

Another possible reason is extra spaces after the bracket.
If it is last definition of the file it is also possible that newline
character does not follow the bracket.

I think the following simple script demonstrates the problem:
f=: 3 : 0
0
2w
3
)
|
|ill-formed number
| f=: 3 :0
|[-5]
The line number [-5] gives the script line where the error was detected.
The script lines from the start of the definition up to the closing )
are taken in as a noun that is fed to the 3 : . The ill-formed number is
not detected reading the lines to build the noun, and is detected when
building the explicit definition.
You need to look at the definition (from the name up to the closing
paren indicated in the error message) for an ill-formed number. Coloring
numbers might help.
There are similar situations with open quotes and control structure
errors, but in those cases there is additional information in the error
message. Perhaps we should provide similar extra information for
ill-formed number.

Dear Paul,
Just to continue your education.
Here is something I got today. After collecting many e-mail
addresses, this company probably used their own list to send
out their advertising! These guys scan every news group and
use every trick they can to collect e-mail addresses.
The profit margins are HUGE. It costs about a dollar to make
one disk. Put them in a case or a sleve, and add postage.
They are asking 225 dollars each This is a lucrative business.
Also notice that they quote one user who says she is very happy
to have 55 orders based on 10,000 e-mail advertisements!

Thanks Eric for your words of wisdom;
What I find is that the indicated number is from the top of the script and
not top of function.
To try and isolate the problem I copied the bare function to a new script,
the error message then changed to include the word "script__" as below.
�ill-formed number: script__
� fill=: 3 :0
�[-32]
There is absolutely nothing in my script after the closing bracket and the
bracket has been deleted and replaced to ensure a clean end.
This is not a new problem. I have run across this several times and the
debug functions unfortunately don't help

The line number in [brackets] is the line number in the the script where
the error was detected. In this case it is the sript line with the
closing paren. The ill-formed number is somehwere in the definition that
is closed with that paren.

I'm not sure if we've made progress or not. You seem to be making it
more mysterious than it is. The ill-formed number is in the definition
of fill. That is, you have an ill-formed number on a line in the script
that is between the line that starts the definion (that is, fill=: 3 ;
0) and the right paren that ends the definition. Whatever comes before
or after the definition of fill is irrelevant. What you have to do is to
examine the fill definition to look for the ill-formed number. Normally
a quick visual scan looking for things like 123w or 1..2 would do. But
it looks like you have a big definition (30 lines). If you can't find it
by visually scanning, try a more brute force method. Copy the definition
to a temp script and run it repeatedly while deleting lines until you
delete the offending line. Once you know which line to look at, I'm sure
the ill-formed number will leap out at you.

This sounds like an algorithm, something that a
computer or interpreter might be good at, and since it
is a native speaker of the language, it might be much
better than a human.
Do I hear a call for better diagnostics / error messages.

The place for phrases is the 'latent expression'. And it's never
too late to do it in one's profile. I wouldn't be surprised if somebody
already have that. It's much less obstrusive in the session log,
and more useful -- for copying and running. Not many would be
happy with an irriating pop-up tip demanding an extra mouse click.
Can one make such customised tip in VS, or other integrated env.
and throw in lunar phases?

I have a msAccess database defined and registered in ODBC.
As long as I do not define a special username and password for this
database I can access
it from J 4.03a without any problems.
However if I define a username and password I got in J4.03a the error
message :

so as if the database is not registered but if I do the same under
J4.02a it works...
eg: connectionhandle =. ddcon'dsn=dbname;uid=donald;pwd=duck'
I ran into this problem on Windows 98+95+NT 4.0.

Global assignment displays while I am doing the assignment but
after that it does not show. Names is a strings phenomen it shows

I would like to be able to assign different colour to user defined verbs in

so that doing names '' would show me different colours for verbs and nouns and

Does it sound reasonable to swap meanings of the Ctrl+Up/Down (Scroll
screen) and Shift+Ctrl+Up/Down (recall previous line)?
Recalling the previous line is involved much more often screen
scrolling, so it should be assigned combination with less keys. I don't
even mention that this is closer to previous assignment for prior lines.

OK Eric, I finally solved the problem.
You were right it had nothing to do with the closing bracket but was in fact
a series of problems within the function.
I had used _var rather than -var in 4 lines.......very simple!!
I do find it interesting however that it ran without error for a week before
the message occurred and then shut me down.
APL error messages were always too cryptic for my liking.. when I have a
problem I like all the help that I can get. I even find it a pain trying to
set a series of debug stops in a long function without a line count guide.

Probably not in the formal sense you mean. But a help find for [- does
get two hits. The second one, in the Primer, explains it.
There is a point with documentation where more is not necessarily
better. If every detail was formally documented, then there would be so
much material you could not possibly have surveyed it all. Let's assume
[-n] was 'properly' documented, but you had never actually read and
remembered its formal description. The question then is which is quicker
and more educational: search for and study the documentation; or say,
hmmm, looks like a line number to me, create a temp script, key in a few
quick experiments, and see what it really is.
I'm not arguing against better documentation. But let's not forget what
poweful tools we have in deductive reasoning and a system where
experiments are easy and rewarding.

<snip of an intelligent argument, on both sides, about documenting
`everything'>
I think Eric makes a point that is important enough to emphasize,
not that there was anything wrong with questioning the documentation
involved in this particular problem.
_Nothing_ would be worse than having a document that described _every_
possible error. I used to work with a DP manager who's favorite phrase
was `... ok, I can bury you in that ...' whenever information was
requested. He quickly taught everyone that _more information_ was often
worse than less.
There's a certain `gotcha' aspect to documentation. Somehow (bad)
documenters love to be able to say ` ... no, that _is_ documented
in sub-paragraph 6b on page 383 ...' as though this were a help to
anyone. What constitutes `good' documentation is much harder to
describe: clarity, conciseness, focus, findability, ... all have a part.
It's not that I'm particularly in love with the way that errors are
handled in `J'. However, it does seem to me that: (1) they are handled
consistently; (2) they are handled rigorously; and (3) they are handled
in some way that makes sense to someone smart (not me, but at least
someone else who happens to be smart).
As a result I find that I usually can (1) believe them; (2) gradually
figure out what they mean; and (3) gradually improve at figuring out
what they mean. Note that typical Windows errors have none of these
characteristics, although I have many volumes on my bookshelf that
purport to help me with `Windows error analysis'.
Years (perhaps too many) of education lead me to believe that the
easiest error diagnosis processes _aren't_ always the most instructive.
Js are, IMO, not bad in comparison with most of the other alternatives
that I encounter daily...

The first time (years ago already!) I ran into [-n] in an error message,
I began counting backwards in the script. I suppose I _should_ have
known better: after all, if you really wanted to say, in J, 5 lines from
the end, you would have given the message in the form [_n]. But I think
my initial reaction was the reasonable expectation that a neophyte, or
not-so-neophtye, might have. Which is why I queried documenting it.
I agree that you cannot document everything, and for the reason stated.

For user-defined objects, would I assume correctly that the problem is
one of time-of-binding -- that the interpreter simply cannot always know
what part of speech a name is?
If that's the reason that nouns and verbs cannot be differently colored,
that doesn't preclude, does it, differently coloring primitives (or
user-defined objects whose part of speech is known)?
For beginners, in my experience, recognizing the different parts of
speech is a major learning difficulty, and coloring could help. A
beginner might not actually know yet which color goes with what part of
speech, but at least she would be alerted by the differning colors.
That's just speculation of course!

I'm not sure exactly when ppc support was introduced. Since your J about
box doesn't mention 68k or ppc, then it predates this support. To get a
ppc version, you'll have to get J4.02. It will run much faster
(certainly more than 5 times faster) than the emulated 68k version.

I doubt that we can justify the effort to fix this. We don't have a test
environment and there would be little interest given that there is a ppc
version that will generally run faster and better.

Bug:
I tried to use Ctrl F to find text in the .ijx window. I got this
error message:

The following are typos that were in previous versions and are still in
J403:

The click the Build button.
Should be "Then click the Build button."
)
----------------------------------------------------------------------
Help, User Manual, Window Controls, Menus
This displayes the text item name, and if selected, the Windows result
contains the name item1.
Should be "displays"
----------------------------------------------------------------------
The main help menu still has an item "User". I found this to be
unclear and inconsistent with usage elsewhere. I would prefer "User
Manual".
----------------------------------------------------------------------
Help. Foreign conjunction 9!:2 y Default Displays. The

OpenGL printing (User Manual, Window Driver

Printing OpenGL images is not directly supported. However, it is
possible to get reasonably good printing of OpenGL images by creating
a bitmap RC, drawing to the bitmap, and then printing the bitmap. If
the bitmap is not stretched to much to fit the printing area the
quality of the printed image is good.
Should be: If the bitmap is not stretched too much . . .
----------------------------------------------------------------------
User Manual, Window Controls, Menus
To add individual items to the popup menu, displayed when the menu is
selected:
wd 'menu item1 "item name"'
This displayes the text item name, and if selected, the Windows result

You're analysis is 100% correct.
Configure|Color already provides what you ask. You can color primitives
according to their class. That is, you can already make primitive nouns,
verbs, adverbs, and conjunctions different colors.
This is done with keywords. You can do lots more with your own custom
keywords.

Ctrl+f works for me in the ijx window. So there is probably some
specific situation required. Can you reproduce the problem? What is the
simplest sequence of steps from starting J to the problem? Does the form
show?
Thanks for the list of typos. We'll see if we can't get at least some of

Eric;
I just retried Ctrl F. I invoked j403, typed in a sentence, and told Ctrl F to find
"the" and it worked fine.
What I was doing before was flipping back and forth between InfoSelect and J, using
the clipboard to copy text. The help window was open most of the time. I ran a ton
of labs, very quickly. There were a lot of pbc windows open from the OOP lab.
(This shouldn't be a problem - I have 256 MB RAM.) Then I tried Ctrl F and got the
error message I reported to you.
I realize that this isn't much help to you.

Italic is an checkbox in the Edit|Configure|Color dialog.
Bold is not supported, because the spacing of bold characters is
usually a little wider than for regular characters, so output may not
line up properly.

J403 helps in a couple of ways. You can use Debug to set stops on
specific lines, and the utility dbstopme inside a definition to set
stops on all lines after it is executed. For a description, load Debug
(Ctrl-K) and read the Help.

What about some (automated) display that would affix the appropriate

Here's one to toss into the discussion...
I find in many cases that it is easier to make changes in my forms directly
rather than using the form editor. Especially for simple size and position
changes on controls. To do this I like to move the xywh numbers into
uniform columns. It makes it easy to see alignment errors. Also I put
blank lines between logical sections of the screen I'm designing, like
before a group box containing related controls. But when I exit the form
editor it writes out all the lines in my code again and I lose the easy to
read lined up columns and blank lines. Could we get some optional 'pretty
print' for our forms? Lining up the xywh's and perhaps the name & type of
controls as well as preserving blank lines?
Thanks,
Peter Nichols

That's an thought, given that the Vocabulary page uses different faces
to distinguish different parts of speech.
Actually, I never liked the differing face treatment in the printed, and
on-screen copy of, the Vocabulary. I much would have preferred color --
I do not have any form of color-blindness -- but obviously that was out
of the question for printing the manuals.
Taking this to the nth degree: one colors the (names of the) primitives
in the on-screen Vocabulary using the same scheme as one is using in
editor windows ;)

I believe it's not a good reason at all. What if one selects
Arial for my J font which does not line up at all.
It's the use's decision.
Why in many other IDEs, HTMLers, etc. bold in Courier works fine?
Courier is the most feasible font, though not best for uniweight
layout. But with bold and underline it would gain really
new perspective. BTW, I attached a picture which shows that Courier
draws in bold without the shift problem.
Courier, worse so ISIJ, Lucida, etc, which are thin line fonts
(unlike Fixedsys or 'Proper' Terminal) are very difficult to get many
distinguished color combinations for. E.g. blue easily mixes up with
cold shades of red (magenta), yellow with light shades of green, which
easily loose readability on dark because of thinness of the font.
I tried to adjust some useful color combinations, but very soon the
text starts to look like schizophrenic nightmare.
Colors are good, for 2-3 different uses only. However that would be nicely
complemented by couple of weight/decoration font variants.
Underline does not have to do with lining up whatsoever.
So why not include it?
Frankly out of all other options Italic is estheatically the ugliest -- on screen.
Speaking about fonts. If the desktop option is Small Fonts, J system
understands Courier New 11 size as 9 size, and so on. Is there any reason
for that. With every new version of J I first check this, but it never gets adjusted.

This is a nasty problem that I'm afraid won't get fixed in this release.
The limit error is because the call stack is full. You are suspended
with a stack so full that there isn't room for a stack entry for the dbr
call to clear the stack.
You can recover from this without shutting down J by using 13!:0 instead
of dbr as this does not require a new stack entry. That is:
13!:0 [ 0 NB. clear stack that has hit the limit
We will add this to the debug documentation.

> ... 'Proper' Terminal [font]
Speaking of this:
I must admit that I consider this Classic IBM Terminal font
in its orginal form (i.e. the pixel set as introduced with
the original 8088 PeeCees, the Monochrome Display Adaptor
and the loooong afterglowing green phosphor monitors) to be
the most beautiful screen font ever made.
I'm refering to the slightly knobbly font with the serifs.
Unfortunately, when I set make "Terminal 9" my default font in J,
I will get it sometimes successfully. There were 2 possible
problems occuring:
(1) Instead of the knobbly font, I'd get an ugly, sans serif, linear
font. This appears to be some problem with Windows not with J:
Other Windows applications like the DOS box or the Hyperterm
have the same flaky behaviour.
(2) In earlier releases (3.x, 4.01, cannot say right now about about
4.02/4.03), J would sometimes switch to the font, but use wrong
font metrics. Erasing characters backwards would cause a garbled
display. This could well be fixed now.
I'm using two different releases of Windows95, the German version
each time. Since that environment is basically not reproducible
for the ISI guys in Toronto and very erratic here, I'd be very
happy about reports by others how at least to reproduce the problem
deterministically. The behaviour is very erratic and I guess dependent
on the previous history of font caching and font scaling.

I agree that bold would be nice.
The problem is not 'lining up' in a visual sense for a human reader, but
rather the work required to manage things like mouse selections. This is
quite simple with text in a single, fixed pitch font. It gets much more
complicated with different char widths.
The editor only works properly if every character has the same width.
We ran the first versions of the editor with bold support. Most ttf
fonts create bold by making the char a pixel or so wider. This confuses
the editor and is unworkable. The only common font that I could find
that doesn't do this is Courier New. And even it makes the chars wider
in larger sizes.
So, I decided to not support bold in this release. I will look at this
again for a future release as I agree it would be nice.
In running experiments from your comments I discovered that I had
inadvertently ignored a choice of bold for the editor font. There is no
width problem if everything is bold, and it might work better with some
of the richer color schemes. I will reenable the ability to specify bold
for the session font.
Your suggestion of underline is interesting. In a few quick examples it
looks pretty good for some things. I'll consider adding it to the
smcolor command and see if Chris can add it to the color form.

And here I thought I was the only one who edited form definitions by
hand. It was something I sort of felt I should keep secret. Using a few
keystrokes when a big visual tool would only take slightly longer seems
like heresy. At least I have the excuse of having been editing them
since before there was a visual editor.
The form editor is very understanding in reading form defintions, but is
quite rigid in how it writes them. This is implemented in C and since
people's taste in things such as pretty are often at odds, I am not
willing to even consider adding something like this in the form editor.
However, this could easily be done by a nice little tool written in J.
It could pretty up the form definition in an open script in myriad ways
to suit everyone.
Sounds like a great chance for some ambitious user to make a nice
contribution to the cause of J programmers everywhere!

Another useful line that does not supported by form editor is
setfont xxxxx "Courier New" 12;
It simply drop it down from form definition. Certainly, one can put this
into form_run handler, or
put it into final version of the form and than (to prevent its
unintentional deletion by form editor) move line
rem form end;
to the very beginning of the noun. But this is something that in russian
is called 'manual sunrize'.

Errors in try are ignored and execution continues in catch regardless of
the debug state.
The change with this release is that a stop error (explicitly requested
by dbss) is honoured and will suspend execution in the try block. This
seems both useful and harmless to your concerns.
Have you observed otherwise?

In-Reply-To: <A12A4ACD69B4D011BB960020AFFBF108029E9096@exs02.ex.nus.edu.sg>
This is somewhat off-topic for a J forum but since several readers
enquired...
K was discarded mostly on the ground that it was costing too much (a
valid complaint, IMO; you can see current prices on the Kx web site and
it used to cost even more) and for a number of political reasons that
I do not fully understand and that I probably couldn't expatiate about
in a public forum even if I did. If you wanted to really understand what
happened, you would have to consider 3 kinds of factors: the personality
of the "K group" people (their supporters included), the IT and business
cultures of Morgan Stanley (where all the key K people came from) and the
culture and politics of the "old UBS" (the company now called UBS is
really SBC). I simply do not have enough information to perform such a
full autopsy, at least not without badly botching the corpse.
One thing is sure, however: the people behind K at UBS did a good job at
selling K to the the top brass (even securing for Arthur Whitney an
extravagant contract whereby he kept ownership of K even though it was
largely developed at and for UBS) but were hugely impopular with many
developers and with key managers (the trading desk managers that the K
group was supporting), both at the New York site and abroad. Relations
were particularly frayed with London, an unwise state of affairs since the
investment banking arm of the old UBS (like Warburg Dillon Read today) was
headquartered in London and run from there, not from New York or Zurich,
where their backers were. They also made the mistake of remaining
aggressively Unix-centric at a time when the bank was moving to NT in a
big way and desk managers were clamoring for an NT version of all their
apps. What is now Kx has since swung to the other extreme (most of the GUI
development is now done for the NT version, I understand, with the Unix
versions being sold as back-end -- i.e., server -- engines: very much the
J situation) but the harm was done. An early NT version was finally
delivered to UBS (can't remember the precise timing) but never used.
Finally, the whole notion of K as an in-house language was probably bunk
(i.e., too hard to justify/pull off). Yes, I know that's how A+ works at
MS but, as I implied above, what works at MS may not work elsewhere. As an
ordinary 3rd-party software supplier, Kx almost certainly has an easier
time selling itself now; it is also less vulnerable to the vagaries of its
relationship with a unique client.
In any case, when UBS was merged with (actually steamrolled by) SBC,
it was decided not to cherry pick but to adopt wholesale the IT
infrastructure of one or the other merger company. In the swiss retail
operation the "old UBS" prevailed but elsewhere it was decided to
standardize on the SBC infrastructure, which means K would probably have
been discarded at that point anyway, like nearly everything UBS...
As for where things stand now, everything has been discarded, although
some analytics are being rewritten (mostly by me!) and recycled, either as
Java or C++ apps.
I don't think one should wildly extrapolate from the sad story of K at
UBS because (IMHO) a number of gross political mistakes were made but it
certainly serves as a counterexample to the fiction that all you need to
succeed is high-level backing. In the case of K, the top-level backing
they enjoyed (up into the office of a counsellor to the UBS CEO in Zurich,
also an Iverson, incidentally) actually hurt them, first because the mere
notion that they had this kind of access rankled nearly everyone else and
second because (or so I suspect) it made them underestimate the necessity
(and the difficulty!) of winning over the layers standing between them and
the top brass.

Eric, Et Al,
Would it be possible to leave off the pretty print idea? Having come to
my senses, I realize that with all the best intentions, agreement on
"pretty" would be difficult. However, if the C code could just preserve
the blank lines and leave the spaces in the xywh numbers, even if digits
got inserted or deleted; I would very happy. Is this option more
doable?

To export bitmap graphics there are two ways:
1. Alt+Printscreen then paste to your favorite graphics editor
2. use glsavebmp the appropriate isigraph control
then paste to your favorite graphics editor
To export vector graphics there are two ways:
- use glsave the appropriate isigraph control
then paste to your favorite vector editor
(Xara, Corel Draw, etc)
- then use WMF2EPS or so from CTAN to convert the
graphics from WMF to EPS.
I tried the last one. It works fine. However the estheatical
result of Courier font on the plot's output is much inferior
to the results you get with more PS oriented systems. cf METAPOST
for TeX.
In general, I believe that having the 'plot' package is one
of the major breakthroughs in J, making it truely powerful for
scientific, calculation researchers, professionals. It's great
for screen work. A natural extension would be to have this screen
part as a previewer and with a single mouse click convert the result
to an importable vector/hi-res bitmap image for printing.

Do you mean that jopen is not defined in the z locale? This has always
been true.
However, it is defined with the rest of the j component files in the
jfiles locale. Use jopen_jfiles_, or if you wish, assign this to
jopen.

Here is a first go at a form pretty printer. We can include this in
the Project Manager script pretty printer.
To experiment, download the following, unzip into your J403 beta
directory, load J, and enter:
load 'ppform.ijs'
Try the experiment.

Fine. Can you do also better looking menu definitions? This kind of pertty
printing is important when you print code for documentation.

Even better is not typing the same type of code over and over for another
form associated with another table or view (of which there are tens or
hundreds in any org.,). An alternative for many cases is to write code to
lay out the form automatically according to a set of rules. Buttons,
labels, edit areas, drop down lists, just represent a real estate problem on
the screen - a much smaller problem than a multi layer PC board. You can
even give the user menu options to change the prefered layout pattern
according to a different set of rules or to display only specific fields.
Furthermore, you can tie the form to meta data in a dynamic dictionary ...
Given that J is interpretive, auto code generation for forms layout at run
time is one of the benefits.

The following simple example works properly.

dbr 1

I have had troubles with try./catch. and :: in the
past (Roger promptly fixed them), and I was left with
the impression that each verb has some responsibility
for implementing it properly. So, if there is a problem,
it's probably not a general problem, but one specific
to the verb; so you need to be specific in your trouble
report.

Why is it not assigned to jopen like the other jfile functions?

Yes! I love it. One tiny quibble, could you put the semicolon directly
after static? And also Anssi's suggestion of sprucing up menues is good
too. Thanks Chris, I really appreciate this.

Because jopen is not required when using component files.
In general, cover functions in the z locale are created only when
necessary. This helps keep the number of definitions in z to a
minimum.
Of course, if you use jopen and jclose a lot, you are free to make the
definitions yourself.

Ok, I thought that jopen had to be used to open the file you were
reading. But I just tried it and you're right. You can just start
reading. Thanks Chris.

Subject: Jforum: Typos
Eric;
Recently I posted a list of typos. You responded:
> Thanks for the list of typos. We'll see if we can't get at least
> some of them fixed.
Most of the typos are minor. They should be fixed, but it's not too
big a deal if they aren't. I checked what I consider to be the most
important problem and it has not been fixed. I want to give you my
reasons why I think that's it's important that it be addressed. This
is the one where text after a quote is colored when it isn't
appropriate.
Some people have suggested that J looks like shareware. I disagree
with this. J is focussed on functionality. The look and feel are not
flashy, but they are adequate. The one area where J looks unfinished
is the above. Here's another example of it from the OOP lab:
(1 of 70) Overview
This lab is about Object Oriented Programming.
It covers OOP ideas and terminology and shows how to do it.
)
(2 of 70) Overview (ctd)
Lab 'Locales' is a prerequisite. However, if you ignore
details you can jump right in, and get back to it later.
Lab 'Grid Examples' has OOP examples and should be done after
this lab.
)
(3 of 70) What is OOP?
OOP is modular programming.
Building an application from scratch as a monolith is a
recipe for failure.
It is better to build and test small modules, and then
combine them to build the application.
It's best when you can use existing modules with a few new
modules to build new applications.
)
Supposing I was a suit (as I have been). A programmer has strongly
recommended to me that the company use J. So, I sit down with J to
evaluate it. For sure I'm going to run a couple of labs. Suppose I
start with the OOP lab, and I see the three panels above.
Having "Locales" and "Grid Examples" in a different color to the rest
of the text seems eccentric to me but, ok, I can live with it. But
having "'s best when you can use existing modules with a few new" in a
different color is clearly wrong. My reaction would be "gee, if
there's big problems with something as simple as putting text on the
screen, how many problems must there be in the core language?" And I
would mandate that my company not use J.
If you want to get a feel for for how this kind of thing looks to an
outsider, take a long look at the Lingo Allegro web site. Browse
through a bunch of the pages. You will see a ton of spelling errors.
What would your reaction be if you were a suit evaluating whether to
hire them? "These guys want to install high tech solutions in my
company, but they don't know how to use a spell checker? I think
not."

You can probably always find spelling errors and faults
if that is what you are after.
Rather than pointing at what is wrong I usually like
more to see suggestions about how individual items
can be made better. Sweeping generalizations are
never very productive nor leed to any positive reactions.
Gradual improvements always lead to big improvements
in the long run. J has come a long way with very little
resources that way.
I find that noting something that may need to be improved
and making a suggestion on how it can be made better
is by far the most effective way of getting things done.
I have sometimes had to wait quite a long time for some
of my suggestions but most of them do appear.
It is very rewarding to see how the interest in J has grown
over the years and there are a lot of things in J now
that none of us would have dreamt were possible.
The colouring experiment has many side effects and
will cause a lot of confusion but it also has a lot of
positive sides. I for one am in favour of living with
some of the strange effects of the colouring for a while
and gradually work them away.

I agree. I hated this when I first saw it and I hate it even more with
time. I've thought about it and couldn't figure out what to do. When
should it be colored and when not?
The current color logic is simple and fast by restricting the rules to
the context of a single line. The temptation for something like the labs
is to maintain state information over all lines so that you can know
things such as, this unmatched quote is in a lab section and shouldn't
be colored. I really don't want to add that complexity. For one thing,
with a very large file the editor would become noticably sluggish as it
has to scan the entire file on every keystroke!
But, your message has given me an idea that I will try out.
The coloring of unmatched quotes is disturbing in text but quite useful
for code. The question is how to distinguish without too much work. The
solution doesn't have to be %100 (I don't think it can be), but it
should work most of the time, particularly for novices and suits.
What I'm going to try on an experimental basis is to color unmatched
quotes only if the caret is on the line. This may be a good idea or a
lousy one. I think the only way to tell is to let the forum try it for a
few days and get feedback. I'll try to do that today.

Here are usages of apostrophe from your message:

shouldn't
don't
I'm
Rule: if ' sign is between two alphabetic characters and to the left or

When this problem occurred in the past, I had to first open an MS-DOS app

Only then did it become available to GUI Windows apps. Since I used

Oddly enough, the font is always available in NT.

Subject: RE: Jforum: color shchemes
> ... 'Proper' Terminal [font]
Speaking of this:
I must admit that I consider this Classic IBM Terminal font
in its orginal form (i.e. the pixel set as introduced with
the original 8088 PeeCees, the Monochrome Display Adaptor
and the loooong afterglowing green phosphor monitors) to be
the most beautiful screen font ever made.
I'm refering to the slightly knobbly font with the serifs.
Unfortunately, when I set make "Terminal 9" my default font in J,
I will get it sometimes successfully. There were 2 possible
problems occuring:
(1) Instead of the knobbly font, I'd get an ugly, sans serif, linear
font. This appears to be some problem with Windows not with J:
Other Windows applications like the DOS box or the Hyperterm
have the same flaky behaviour.
(2) In earlier releases (3.x, 4.01, cannot say right now about about
4.02/4.03), J would sometimes switch to the font, but use wrong
font metrics. Erasing characters backwards would cause a garbled
display. This could well be fixed now.
I'm using two different releases of Windows95, the German version
each time. Since that environment is basically not reproducible
for the ISI guys in Toronto and very erratic here, I'd be very
happy about reports by others how at least to reproduce the problem
deterministically. The behaviour is very erratic and I guess dependent
on the previous history of font caching and font scaling.

I have noticed this phenomenon first time running new J beta.
My first reaction was that it's kind'a bug of string hiliting.
But then I learned about distive hiliting of complete/incomplete
strings.
Designing complicated rules for string hiliting may be furtile
excersise, whereas there is a simple solution:
include the code that turns off string hiliting at the beginning
of the lab, and then after the end of the lab turn it back on.
Examples of code in labs are usually simple and don't need
string hiliting distinction facility.

Interesting. But it would not work for me as a programmer with:
f'this is an open quote
I feel strongly that the bias should be towards the programmer, not
Brian's suit. We want to coddle the programmer without unnecessarily
antagonizing the suit.
I've been playing with my suggestion of only coloring unmatched quotes
if the caret is on the line. It sounded better to me than it is in
practice.
Chris is going to take a look at it, but currently we both favor the
option of simply removing unmatched quotes in labs.

I see your problem. But the issue of appearance is an important one
in the marketing process, so it would be good if the problem could be
fixed.
First off, I would vote against your proposed solution of only showing
the coloring when the caret is over the line. There are two reasons.
1) When I'm programming I want to be able to glance at the whole
screen and instantly identify mismatched quotes.
2) It doesn't really solve the problem. If the user moves the caret
over the line, the inappropriate colors suddenly jump out. This looks
even more like a bug.
Lest Gosi scold me again for being negative, let me offer three
suggestions.
1) Leave the system exactly as it is, but explain to the user why this
is part of the J environment - it really is a feature and not a bug.
E.g., the first panel of each lab could have something like: "You will
see different colors being used for text that is between quotes or
follows a mismatched quote. This is the same way the programmer sees
code. It is a useful programming/debugging tool."
2) Avoid contractions. Instead of "It's best" use "It is best". This
makes the text a little more stilted, but solves the worst of the
appearance problems. This still leaves the text between quotes having
a different color. This can be solved by delivering the system with
the text inside balanced quotes the same color as that outside them.
The programmer can turn this feature back on later.
3) Write a verb that can reset colors on the fly. Embed this verb in
the code that creates the labs. It would set colors to neutral just
before text is displayed, then turn the colors back on to display
code.
The third solution is the cleanest and most complete, but I would
think that it involves the most work.

While it would be hard to take a position in favor of typos, I'd be
real surprised to find many business decisions that really swing
on `typo detection'. Indeed, few of my managerial decision making
colleagues or executive education students (most of whom had to scan
_hundreds_ of pages a day of information) would ever catch a typo
(or if they did, have a second thought about it. They're typically
thinking about the subject _not_ the presentation.)
People with serious decision problems, in my experience, are _terrible_
copy editors. They are too used to reading too much too fast to worry
much---or even see---tiny details in what passes in front of them.
[Lest I am accused of unfairness, `decision makers are usually lousy
copy editors' is accompanied by a corollary `copy editors are usually
lousy decision makers'...].
So, whatever (if anything) is keeping `J' from corporate adoptions, I
doubt that it's got much to do with details of typography in the `help'
documentation.
Worrying about typos because they impact the programmers or other
`in depth' users makes good sense. Worrying about them because of
some nebulous---and arguable---effect on business decision makers
strikes me as pointless.
Of course, that's just an opinion.

The experience in the field of advertising dictates that even if the
probability of typos being discovered are low, one should not conclude that the
importance of eliminating typos is diminished. The purchasing effect on a
potential buyer who discovers a typo in the presentation of a product is
devastating.
I recommend eliminating all use of contractions and possessives in the text.
It is more presentable, and eliminates the unmatched quote problem, to boot.
Of course, always use the spelling checker. If available, also use a grammar
checker.

You can download script http://members.xoom.com:80/nsg21/jedit.zip.
Its brief description is at http://members.xoom.com/nsg21/jpage.htm
In a couple of words: it assigns a shortcut that comments (or
decomments) selected block. I have not tested it yet in j403 though.

I am not sure about NB; but I have proposed in the
past to have NB:
I would use NB. as local comment that would be
removed after development.
NB: would be a global comment that would stay on
and be used to explain the verb.

There is no need to extend the language to achieve this. Just use a coding
convention such as:
NB. this is global
NB.. this is local
Then all you need do is to write a script to remove all the NB.. comments from your
project's scripts.

I noticed that the new editor supports dragging text to a new location, just like
word processors. In the past I was sloppy in moving the mouse, but now I have to
avoid doing an accidental drag. It's a nice feature, but one needs to be aware of
it.

By the way - the verb 'edit' doesn't know what to do with this

Looks OK to me.
I''ve tried double quotes for singles but they stay doubled.
As is usually is the case, a very nice tool leads to all kinds
of side effects.
By the way - the verb 'edit' doesn't know what to do with this
noun either.

I am puzzled why the following does not box up things the way I expect:
test1=. (100;'x');(200;'y');(300;'z')
I thought test1 should give 3 boxes within each of which there should be 2
boxes with the first box corresponding to the first member of the item in
parentheses and the second box corresponding to the second member. Instead
test1 gives 4 boxes with only the first 2 boxes behaving as expected.
However, I get what I require if I write:
test2=. (100;'x');(200;'y);<(300;'z')
Why does the more "natural" expression in test1 not work the way one would
expect?

The suggestion below does not work -- trying to make the definition
NB=: 0 : 0
or even
NB=: (0 : 0)
causes the cursor to be at the left margin and makes the interpreter
wait for further input to conclude the definition.
The alternative,

I've looked at a couple labs in which apostrophes are used in
contractions in text, e.g., "Let's". The coloring that starts at the
"unmatched" single quote is truly distracting.
Until a more coherent approach -- if there is one -- can be worked out,
it might be a good idea to remove all such contractions from the
distributed labs. And, if this occurs (didn't check it myself), rewrite
so as to avoid all possessives formed with apostrophes.

I am now using another browser and did the same
copying and did not get any strange characters into
the ijs.
However.......
Having started to look at this I began to look at how J403 handles
Icelandic characters.
It does NOT.
I have J402 here to compare and I have tried several fonts.
In J402 "Times New Roman" looks good as default and ansi.
J403 "Times New Roman" displays completely wrong.
This is a major drawback !!!!!
On the bright side then I managed to get the ftp script to work.
I have never given it a try before. I just read through it but now I
tested it and it works just great.
Well done Kirk !!
I was looking for the ftp script on jsoftware and could not find it there
It is not together with J403 either. It would be great as a lab !!
Is there a search possibility to look through the jsoftware webpages?

x;y is (<x),y if y is boxed, and (<x),<y if y is open.
The reason for this is that this way you can do:
longlist=:'fourth';'fifth';'sixth';'seventh'
longlist=:'first';'second';'third';longlist
...
Which gives a neet list, as most of us would expect.
If x;y was always giving (<x),<y even when y is boxed,
then the above would give the equivalent of:
longlist=:(<'fourth'),<(<'fifth'),<(<'sixth'),(<'seventh')
longlist=:(<'first'),<(<'second'),<(<'third'),<longlist
...
A scary thing to look at...Try it...
So, when the rigth argument to link is already boxed,
one must be aware of link's behavior...
BTW, my prefered way of handling your example is:
test1=._2<\100;'x';200;'y';300;'z'
Better yet, I usually keep everything in a list
and then use J's power to cut it anyway I want...

We decided to leave the color editor as is, and fix up the labs. In
the most recent J beta, some of the labs have already been corrected
(e.g. the OOP lab). The others should be done before the release.
These fixes should at least let you run the labs without looking too
bad, assuming you have the default, or a simple, color configuration.
Note that it will not solve all problems. For example, we changed some
quoted text to use double quotes. If you have set a color coding for
double quotes, that will show up in the lab text.

In addition to the explanations that Paul and Chris gave,
I should point out that in J ; is a verb that is syntactically like
any other. In particular, in a phrase such as x;y;z;a;b;c;d
the instances of ; can not look forward or look back;
each instance of ; is given only its left and right arguments.
This is not the case with the ; in APL.

I noticed that there is no provision for a password in the Oracle 8 ODBC

I would appreciate any help on this topic... I am sure someone out there
is connecting to Oracle with J...

Date: Thu, 27 May 99 18:52:35 +0000
I can recommend two free programs I found on the web today.
One is called Snapper and the other one called Windiff.
Snapper shows which files have changed between different
distributions of J and Windiff displays nicely in detail how the files
have changed.
I have used Windiff for many years but I always thought it was a
part of C++
As I needed Windiff and did not have it on my computer I started
to look for it on the web and found Snapper too.

It depends on the buyer (or reader). My wife is very critical of spelling and
grammatical errors. When she sees one it turns her off to the author or product.
Me? I could care less. What upsets me is incompleteness either by accident or in an
attempt to mislead.

I have checked the new 403a07 beta for fonts and hiliting.
It's nice to have the underline alternative. However, 2 problems:
1. Not always the underline is visible. Especially, in most widely
used Courier New at 9pt (wich corresponds to J's 11pt):
In italic/underline it shows, though, in 10/12pt it shows
by itself. But the 9pt (J's 11pt) is so critical. Can it be fixed?
2. In 'control words' item, when you select underline, together
with the "word." (word dot) the right adjesent spaces are underlined:
word. another word
~~~~~~~~
Of course it's not seen in color/italic, since the spaces are invisible,
but shows through in underline.

I just use the font provided by Windows with the size and options
requested. I don't think there is anything I can do about how underline
looks at a small size.

The repository users can already compare their existing J standard
library against the most current or any other release. The important
point is to relief YOU as a user from mainting directories with
different versions, which quickly accumulate. (Hi there, beta testers!)
For example, the following command quickly shows what happened
between the J libary as stored on your computer with what's
now _officially_ current and going to be part of the next release,
for brevity restricted on the system/main hierarchy:
cvs diff -cu -r HEAD system/main

So much about seeing the differences. Users can now just say
"cvs update" and --presto-- they will get the revised format.ijs.
The recent poll I made on the J/Unix mailing list gave a clear
picture that J'ers do not have the requirement to support multiple
J releases simultaneously on their systems. Well, I did, for
obvious reasons, but only until I switch over to the repository.
Therfore, the next Unix release will revert back from the
/usr/local/lib/j-$JRELEASE/... scheme to the old simple
/usr/local/lib/j/... directory -- but with the added CVS meta
information already in place, so that people can stay sync'ed
with the official library immediately.

All this talk about the J editor. Does that mean that
the development environment for J is now called
J editor?
I have always preferred to call it a studio because it
is a lot more than an editor.
It took me a while to get the hang of it. I was looking
for an editor but did not find any.
It is possible to say that you give away J for free and only
sell the editor. I still prefer to call it a studio. Parts of the
studio is obviously an editor.
And by the way. I am having a problem with Icelandic characters in the editor.
They display ok in the form editor
and on forms but not in ijx nor ijs as they used to in J402.
I am using J40307 even if the help about only tells me
it is J403Beta.

Personally I use editor as part of, as you call it, 'studio' 100% of the
time I work with it. (Actually, not exactly 100, but it is very good
approximation) This relates not only to J environment, but to any I ever
used.
That is why convenience and power of editor strictly determines
convenience and power of environment ('studio'). And that is why I am so
concerned about editor.
Among all those new editor's features there is only one that I've found
useful to me: possibility to turn off syntax coloring. And I was just
curious, maybe there is something else almost the same usefull?
> It took me a while to get the hang of it. I was looking

Sure. If you wish you may call it 'studio'. Then the questions would be
Does new 'studio' allow to assign J verbs to different key combinations?
Is there programmatic access to left 'margin' (where bookmarks are
placed)?
Can user place something on this margin?

Sure. The same way as parts of the computer is obviously computer

You are lucky. I have problems with russian characters and this hurts me

I might add that if the Icelandic characters are permanently gone in this editor
then I would like to be able to chose the old editor as a config option.

Could you give me more information on this problem. As far as I can tell
the new J code editor (ijx and ijs windows) supports true type fonts
with ANSI and OEM character sets the same as before. What font are you
having problems with? How does it display? Note that it must be a fixed
pitch font. If you select a font that isn't fixed pitch, your selection
is ignored and you get a default system font.

You're right. As far as I can tell this is an unintentional change. I'll
check with Chris, but my immediate reaction is that it is a bug and it
will be fixed.
There is a new command, smgetscroll, with this release that gives the
scroll position of the top line. You could model either definition of
smscroll from the other.

I am not getting Times New Roman which I usually used
before in J402 and I tried a few others at random and
did not see any. Notepad displays Icelandic chars with
many of the fonts that J does not.

In ISIJ they do not display at all in ijx and they display as
black boxes in ijs.

I tested all variations of fonts and settings and now I
do get Icelandic characters with this:
courier 20 ansi
courier 20 default
courier new 20 ansi
courier new 20 default
fixedsys ansi
fixedsys oem
fixedsys default
lucida console default
lucida console ansi
marlett ansi
modern ansi
monotype sorts ansi
ms outlook ansi
mt extra ansi
roman ansi
script ansi
system ansi
system default
terminal ansi
wingdings ansi
I bet some of them are not really there and the system is picking something
instead.
For exempel windings. Notepad does not display Icelandic
characters with wingdings but J does !!

Times New Roman is not a fixed pitch font. You must use a fixed pitch
font in the new J code editor.

"Replace all" should do "find from top" and then "replace forward"

Thanks for pointing this out. The name will be changed to 'Replace
Forward', leaving the existing behaviour unchanged. To replace from
the top, first press the 'Find From Top' button.

Subject: Jforum: DICTIONARIES IN J
Date: Sun, 30 May 1999 00:53:55 +0800
Python and K directly support "dictionaries". For example, in Python, I can
write a salary lookup table for, say, 3 employees as a dictionary of the
form:
salary_table =
{'bill':(200,300,400),'madeline':(150,200,250),'alan':(160,170,200)}
Bill's salary would then be given by the following function call:
salary_table['bill'] and would produce the required result:
salary_table['bill']=(200,300,400)
How would one similarly implement "dictionaries" in J? Thanks in advance for
any advice.

Here is a quick and dirty method. Dictionaries is a nice idea and I
would to have a script that implemented them. It likely would not have
to be part of the interpreter.
DAT=: _2 [\ 'bill';200 300 400;'madeline';150 200 250;'alan';160
170 200
get=: [: > [: {: ] {~ ([: {."1 ]) i. [: {. [: boxopen [: , [
DAT

+--------+-----------+
|madeline|150 200 250|
+--------+-----------+
|alan |160 170 200|
+--------+-----------+
'bill' get DAT
200 300 400
'alan' get DAT
160 170 200

Dictionaries can be implemented by having separate arrays
for the keys and the corresponding data. Instead of using
the key values directly as indices, you'd use keys i. kv . Thus:
keys=: <;._1 ' bill madeline alan'
data=: _3[\ 200 300 400 150 200 250 160 170 200
(keys i. <;._1 ' madeline bill') { data
150 200 250
200 300 400
data=: 222 333 444 (keys i. <'bill') } data
data
222 333 444
150 200 250
160 170 200
When designing the keys it is important to select a representation
which has fast support in the dyad i. , such as a boolean, integer,
or literal array, or a vector of boxed strings ("keys" above).
You can readily verify the fitness using 6!:2 .

I've got a neat implementation of dictionaries (3 different classes, for
general text keys, for tokens, and for numbers) I'll sort out the code and
send it shortly.

Here is an illustration to see where the problem may be.
Open WordPad. Enter a couple of text lines. Select all (Ctrl+A)
and choose Courier New 9pt font. Now select a word on the top line
and press the "U" button on the toolbar (switch for the underline
style) several times. Notice how the second line below jumps up and
down allowing an extra pixel for the underline on the line above.
Now Select all and choose Courier New 10pt. Do the same as above.
Now the line below does not jump, since there is enough space for
the underline in that font size.
I suspect that the problem with underline visibility at certain
fonts and sizes can cured with adding extra pixel(s) per line.
I believe Windows API functions, like GetTextExtentPoint32 should
provide the necessary information.

I just use the font provided by Windows with the size and options
requested. I don't think there is anything I can do about how underline
looks at a small size.

Windows has option for fonts to be ANSI or OEM.
But for keyboards in national settings there is only
the ANSI option. Prior to beta J403, J 'editor' refused
to accept keycodes of the upper ANSI set above 127, though
it could display them. Now it accepts. However the mapping
is such that it does not correctly correspond to either
ANSI or OEM.
Moreover, currently the Config/Font selection does not
preserve the 'Script' and it always remain 'Western'.
So one cannot even select the proper charset to see the Russian
letters at all. I suppose the same happens with Icelandic.
However, French (Canadian) may not suffer such problems,
since the Western charset includes French letters.

Could you give me more information on this problem. As far as I can tell
the new J code editor (ijx and ijs windows) supports true type fonts
with ANSI and OEM character sets the same as before. What font are you
having problems with? How does it display? Note that it must be a fixed
pitch font. If you select a font that isn't fixed pitch, your selection
is ignored and you get a default system font.

You are lucky. I have problems with russian characters and this hurts me
much more.

enclosed is a project 'dictionaries', unpack it to your user\projects
directory
the implementation is based on the smalltalk Dictionary, class sDict is the
ordinary dictionary with strings as keys. sWDict (Word Dictionary) is based
on Jtokens - ie on the use of ;: to chop the keys, and sNDict uses numeric
keys.
you'll see that the two subClasses sWDict and sNDict inherit most of the
code from sDict and only change how the keys are handled.
each class contains a <test> method, and sDict has some documentation, I'll
add some more if anyone is interested in using this stuff.
load the project from the project manager, then heres your example:
salaryTable=.''conew'sWDict'

Interesting. I now see what would have to be done in order to properly
support underline. It has also made me realize that it might be possible
to support bold with a similar trick. That is, tighten up the bold chars
so that they were of the same width as plain. This might look ok. If
not, then the plain chars could be spread out a bit so that the result
was fixed pitch.
Interesting ideas for the future. I'm afraid we've reached the point of
diminishing returns. And we are out of time. We'll have to live with
these limitations, but keep them in mind for the future.

I don't understand. Possibly because my experiments with English windows
and keyboard give different result than on your configuration.
As far as I can tell the support for J402 J403 code editors of ANSI and
OEM character sets is identical (in function, though the code is
completely different). The only difference is that the J403 code editor
insists on a fixed pitch font.
If I select Courier New ANSI, I can enter code points above 127 with the
alt numeric sequence. For example, alt+0200 displays an accented cap E
in the editor. This behaves as expected. Or I can cut/paste from CharMap
or other apps.
Just realized you are probably (Russian and Icelandic) are trying to
work with multi-byte character sets. These might work in the old editor
(as it is a standard edit control), but I think it would get J a bit
confused as I'm not sure how the multibyte codes would get passed
across. There is no multi-byte support in the new code editor.
Eventualy it might be possible to have unicode support both in the
editor and in J and this would be the proper solution in the future. But
the future is not now.

Thanks to Roger Hui and Simon Garland for their suggestions on how
"dictionaries" could be implemented in J. It seems to me that dictionaries
are a very useful concept but their implementation is non-trivial. Simon's
suggestion to further enhance his project script to provide added
functionality would be welcomed by all.

enclosed is a project 'dictionaries', unpack it to your user\projects
directory
the implementation is based on the smalltalk Dictionary, class sDict is
the
ordinary dictionary with strings as keys. sWDict (Word Dictionary) is
based
on Jtokens - ie on the use of ;: to chop the keys, and sNDict uses
numeric
keys.
you'll see that the two subClasses sWDict and sNDict inherit most of the
code from sDict and only change how the keys are handled.
each class contains a <test> method, and sDict has some documentation,
I'll
add some more if anyone is interested in using this stuff.
load the project from the project manager, then heres your example:
salaryTable=.''conew'sWDict'

I think the answers from Chris, Roger, and Simon show ways to a proper
implementation of kinds of facilities you want.
I wanted to point out other things. Not because they are a better way to
implement what you want, but because they might add to your
understanding.
K and Phython dictionaries are similar to J locales. They are all just
variations on the traditional idea of a symbol table. They differ in how
and in what degree they integrate into the language. It is interesting
to see what the simplest mapping of your K example is in J.
Your K example (simplified):
st = 'bill':(200,300,400),'madeline':(150,200,250)
st['bill']
200 300 400
st['bill']=(100,100,100)
J version:
st=: cocreate'' NB. create new locale (dictionary)
bill__st=: 200 300 400
madeline__st=: 100 200 300
bill__st
200 300 400
bill__st=: 100 100 100
In my opinion, in an example as simple as this, Roger's array oriented
approach will be much simpler to code and debug and will be much much
faster. As the problem gets more complicated and messy and you want to
reuse the code in other applications, then Simon's object oriented
approach starts to have benefits.

I just finished telling Roger I knew about this problem and that it was
an acceptable one. Then your message shows up.
I'm surprised no one else has commented on this, and that lulled my into
thinking it wasn't too important.
Trouble is all that silly parsing and coloring is being done for a lot
of stuff unnecessarily and that can make things sluggish at times.
I will take a look at this.

I see what is happening and it is a bug. Your example displays a large
number of characters in the line. With the file I chose it was 50,000
characters. The code is supposed to truncate after 256 characters to
prevent the problem you are seeing. But the output is coming in many
chunks and instead of remembering it is truncating and just throwing
away the other chunks it keeps adding on each truncated chunk. If you
have the patience to scroll over in your output you will see ...
periodically.
Thanks for the report. It will be fixed.

I have J and I have Oracle 8.
I just have not started to use them together.
Is there a problem?

Here are the messages from may 17th 1999 on the subject, but before you
browse through them let me quickly answer your questions. The method for
opening Oracle fails with any/all J version. In APL+WIN it works because
we use a propriatary DLL that makes the core of APL LINK Version 1 which
gives us connectivity for Oracle as well as Ingres etc. They have
multiple links support through what they call a console. So the syntax
to connect to Oracle in their case is the equivalent of:
rc=.SQAConnect con srv [pwd] [usr] [auto]
con is the connection object name
src is the Data Source name
pwd is the password
usr is the logon user id
auto is the value 'AutoCommit' 'N' or 'AutoCommit 'Y'
rc os the result and what they call the console handle.
So rc=.SQAConnect 'MyFirstCon' 'Oracle' 'unifedh' 'unifedh'
('AutoCommit' 'N') will work fine...
Yes, the datasource is found but as I pointed out, Oracle, for security
reason does not provide for the password to be included in the ODBC
proprieties window.
In the ODBC window, the dsn name is fend4, in Oracle 8, both the Data
Source and what Oracle calls the Service Name are fend4 and they have a
user unifedh with password unifedh. The APL LINK under APL+WIN
connection is done through the DLL from Insight Systems ApS of
Hellebaek, Denmark. Its based on SQAPL for SequeLink, which was designed
by Bjorn Christensen and Morten Kromberg at Insight Systems in 1993.
ODBC Support was added in May 1994.
Question, does that mean that someone has to develop a special package
for connecting J to Oracle or other DataBase like DB2, ESSBase etc. ?
What is it I don't catch in these security issues ?
Now, here are copies of the messages I sent both to the J forum and
Gordon since May 17th 1999. In chronological order:
May 17th to forum@jsoftware.com
I am trying to connect to an Oracle v8 database and can't seem to get
the
connection parameters right.
ddecon'dsn=oracle8;uid=mine;pwd=secret'
always gives me the following:
IM002 0 [Microsoft][Gestionnaire de pilotes ODBC] Source de donn�es non
trouv�e et nom de pilote non sp�cifi�
On the other hand, ddecon'dsn=oracle8'
gives me the following:
28000 1017 [Oracle][ODBC][Ora]ORA-01017: nom d'utilisateur/mot de passe
invalide; connexion refus�e
Which was to be expected.
We also use that database with APL-Link and they seem to go through a
"console"
which is the first parameter (before the dsn) that we pass to their
function. So my
question is: What special wizardry in the syntax (or missing console)
should I do
in order to at least connect to the "thing"
P.S.: Sorry for the french error messages but NT 4 SP 4 is in french
here.
May 25th to gordon@island.net
I tried just about every combination and I'm still stuck...
I have Oracle 8 with a defined datasource fend4, uid=unifedh,

We also use APL-Link with APL2000 and here is the strinq they use with

So, apparently, a "console" is used to pass the parameters to the ODBC

Does that mean we need to do something similar in J ?

Paul,
No one on the J forum seems have advice for you on Oracle 8.
Perhaps you could experiment. Does your method of opening Oracle in
J403 work in J402? Does it work in APL+WIN?
Is the data source found when you list them (ddsrc'')? If not you have
to add it.

Sorry but this does not work with Oracle. Oracle, for security reasons
does not provide for the entry od a password in their ODBC drivers nor
could I find an ODBC driver that would for Oracle. I still can't
connect, I sent other messages to Gordon and will follw through... It
looks like there is something special about Oracle (I'm using version
8). On the other hand, I did try it for Access abd it works fine as you

Hi Paul.
It should work the same way as before - just let out the "UID" and
"PWD"
]ch =. ddcon'dsn=tables' NB. ]ch= ddcon'dsn=tables' 0 <<< was a
typing error - sorry having misled you.
The UID/PWD is now somehow encoded as a number in the result of
the
connection handle.
So you must obviously not care about it.I even tried it with
accessing
DB2 on the mainframe from an NT 4 platform - and
it works.
So.
]ch=. ddcon'dsn=tables' NB. even if the connection is protected by
username+password
sh =. 'select * from tablename' ddsel ch
rc =. ddfch sh,100 NB. fetch the first 100 records
My problem was that as soon as I used "UID" and "PWD" I got this
message that the file is not registered in ODBC.

I posted a message about difficulties to connect to an Oracle 8

following sequences hoping someone can answer me. I translated the
french parts of error messages in bold italic.
Here are the sequences with error message:
NB. First with the Oracle 8 supplied ODBC Driver

NB. End of sequences
I noticed that there is no provision for a password in the Oracle 8 ODBC
driver configuration for any of the two drivers tried, as is the case
for access... Is that something helping ?
I would appreciate any help on this topic... I am sure someone out there
is connecting to Oracle with J...

This is particularly neat - it gives me the basic building block for the
solution in J of the practical problem that I had tackled quite easily in
Python. The problem was: given the current salary of an individual on a
specified annual salary scale what would his/her salary be in n years time.
Using Chris's "get" verb and the bx utility (bx=: #i.@#), the answer is
given by the following verb:
next=: 3 : 0
'd k v n'=. y.
((bx (k get d)= v)+n){k get d
NB. d - dictionary;k - key
NB. v - value to be matched; n -offset from value to be matched
)
Once the "get" verb had been defined, a solution to the problem in J has
turned out to be easy. It would, of course, have been impossible for a J
neophyte like myself to come up with anything like the "get" definition.
I suppose it was easier for me to tackle the problem in Python as
dictionaries are directly supported in the language - in effect, the
equivalent of the "get" verb has been included in the standard Python
libraries.
I think the suggestion of a script supporting dictionaries is excellent as
it would simplify tackling many practical business problems.

js.GetB and js.SetB map the BSTR datatype to J character strings. The
definition for the mapping of BSTR to J character string is to throw
away the extra byte of each unicode character. This is fine and
convenient in 'english' applications where the discarded bytes are
always 0.
Since there is no 2 byte character data type in J, such data must be
represented as J integer lists.
I think you can solve your problem of moving unicode data between VB and
J if you use VB routines that convert between unicode strings and
integer arrays and exchange integer arrays with J.

This is a clear case where input has to come from you. You have the
motivation and you are in the environment where you can and must
experiment. You are in the real world with the real requirements. See
how much you can do with what is already there. Communciate your
experience and wishes back here in the forum.

I find the <get> verb difficult to read, and have never been comfortable with
this use of the cap verb. The following is a variant of a similar utility verb
I've used often:
from=: ] >@{:@{~ {."1@] i. <@,@[
'madeline' from DAT
150 200 250
/K

I recommend keeping the keys separate from the data.
As above, to do anything with the keys (i.e., to do anything),
you have to first do {"1 DAT . As well, if the keys are
separate, and the data are "fully inverted" (one field
per pronoun), the solution scales easily. For example,
you can readily use mapped variables.

This might perhaps be true of the tacit form of "get" that was given,
but otherwise you would surely expect a complete beginner to be able
to write an equivalent to "get" on their first day using J. The
problem is, after all, completely trivial - look up a name in column
0, pick out the corresponding entry in column 1. Or following Roger's
suggestion, look up a name in a list of names, pick out the
corresponding data from a list of data.

yet another reason for having the keys and values distinct is that it allows
you to have a vector of integers (partNumbers, customerIds, whatever..) as
the keys, rather than needing a vector of enclosed integers - makes them
much easier/faster to work with.
see the sNDict subclass in my examples.

You could use wd'wait' for a modal dialog. However, in all cases I have
seen it is possible to restructure the application so that a modal state
is not required. In my experience the extra effort to avoid the modal
state is always repaid in full.
Use ctrl+shift+F to search for wait in the J main directory. The only
place Chris uses wd'wait' is for the verb that handles ctrl+d
(editinputlogs) and wdselect. I think he agrees it would be better to
rework these to not use wd'wait', but has not had time to do so.

Eric,
I had this question in mind few months ago and I did not understand your
answer to avoid wait. The point to the understanding was that you must give
the parent control an owner property. Then it keeps the other forms in
background until closed.

If wd'wait' instead is used in line 004, it will remove every
message in modalform, consequently event handlers in modalform
receive no message at all. This is reason why a non-destructive
wd'doevent' (similar to PeekMessage in winapi) being proposed.
The modal state can be avoided by simply deleting all codes
after line 003, so that the parentform go sleeping inside
system's message loop. Then modalform invokes a callback function
in parent form when it's about to destroy.
001 callback=: 3 : 0
002 result=. out_commu_
003 [and other codes here]
004 )
But I don't if this is a better method or just a workaround.

If you like this kind of solution, you can use the
utilities I offer below. Roger and Simon are
correct that keeping the keys & data separate is faster,

work for me.

After wd'wait', you can do the event dispatching the same way wdhandler
does. You could just call wdhandler, or you can specifically process
events more directly the way wdselect does. I think this has pretty much
the same effect as doevent.

Windows help is mysterious in how it find things (or doesn't). If you
installed the beta on top of an existing J install, it is possible the
old files are confusing help. Try clearing the j directory and doing the
install again. A more likely explanation is that at some point you
opened a J help file from outside of J (for example, clicking it in
explorer). In some cases (but not all), help will then make a copy of
cnt files in a windows system directory. Finding one of these old J cnt
files may be the problem. Do a search for j*.cnt files and see if this
is the case. If so, get rid of the J ones that don't belong.
