Re: ideas on string compression
The best idea currently is probably the Garcia-Wachs algorithm, a
generalization of Huffman coding. See the 2d edition of Knuth's Sorting and
Searching, Section 6.2.2, Algorithm G. See also exercise 6.3 42, an algorithm
shown to Knuth by Andy Heller and Bob Johnson, for front and rear compression.
Compression of sparse tables is discussed in exercise 6.3 4. Storage of random
text so that it is as compact as possible and quickly retrievable is
summarized on page 507. Of the three methods described (Trie search, Digital
tree search, and Patricia) Patricia is the winner. This method was used many
years ago by Luther Woodrum and about 15 years ago by Bob Bernecky. Bob could
probably tell you of his experiences with the method.

Subject: Jforum: Building JDLLServer with Project Manager
In-Reply-To: <3.0.1.32.19990228134241.006d37e4@pop1.sympatico.ca>
After struggling few hours building a JDLLServer-compatible code with J4.02
Project Manager I want to share some of my ideas. It was not easy because
JDLLServer is not a wd-system and building a script with PM loaded some
wd-stuff there that did not run with JDLLServer.
The idea I found is that for JDLL-application you only need
system\main\stdlib.ijs and system\main\colib.ijs. These can't be loaded
using PM together with the application source. However it is possible to
make a separate jdll_lib-project that has sources as stlib.ijs and colib.ijs.
Before you can build it you must turn the code to 'z'-locale by adding a
script that only puts the pointer to z-locale: 18!:4 <'z'
Now my JDLL-application has two parts: a library part and a source part.
And it works!
However I would like to suggest for future J-versions that there will be
provided two versions of standard libraries: For windows and for j.dll.
Thanks,
Anssi

One tactic I have found very successful when building runtime or
automation applications is to run with a "naked J." Turn off
profile loading, (it's a command line option), and just load
bare interpretor sans utilities. If your app has a hidden
library dependency you very quickly run into it.
Also, I always set up my apps to to load only what
they require and I use the the low level 0!:x facilities instead of
load. It's a bit of pain set up your first app like this but the
end result is a system that loads very quickly and is completely
self contained.

Just for the record: the Windows kernel has a standard set of
functions to deal with compressed files:
LZInit, LZOpenFile, LZRead, LZSeek, LZCopy, CopyLZFile, et al.
These are admittedly not string oriented, but at least a portable
foundation for Windows J programs.
On Uniz, the gnu gzip program will give you a libz.a which may
or may not be exploitable. I haven't looked at the details.
Alternatively, folks around partly switched over to "bzip2"
with Burrows-Wheeler block-sorting text compression. Again,
sources are available and linking to a shared lib should be
possible.
Speaking of compression:
Two or three years ago, someone announced a format-tunable and even
auto-tuning logfile compressor in comp.lang.apl, written in J and with
some very nice web pages describing it. I found this system just great
and would like to have a second look at it, but unfortunately I
didn't keep the bookmark back then. If someone could help me with
a fresh pointer to it, I would greatly appreciate it.

On Win32, you can use Internet.HHCLTL or so to create a form

Secondly, there is a way to call a default bowser, similar to
"mailto:" for default mailer. I belive that it is also system

Oleg,
I downloaded and upacked your package -- very, very nice!
I've been planning to do something like this for a while and I thank
you for saving me a lot of work.
I would strongly urge all J'uggler's to take a look at this. It makes
browsing the J script documentation a breeze. It's also a nice
carrot to get people to start formatting their code in scriptdoc
friendly fashion. I revised the new ODBC package primarily for
scriptdoc and now I'm keen to see how Oleg's package renders it.
If there's enough space on the official J website I would recommend
mounting at least a subset of the J libraries in this form.
The only thing I would suggest is somehow supplying a link to
the actual J code that the scriptdoc is documenting: I know users - never
satisfied.
Also could you supply an example of how you build these html files.
The *.bat file in your zip refers to the HTML help compiler. The
hhc.exe is obviously used and I presume you run some J process
to format input files for the help compiler.
Again, nice job.

Documentation Conventions
The following conventions are used to document J system scripts, and are
recognized by the scriptdoc utility.
Scripts are documented in comment lines (i.e. lines beginning with NB.).
Multi-line comments are consecutive lines beginning with NB. with no break.
The first line of a multi-line comment is used for summary documentation.
The script itself is documented at the beginning. The first line describes
the script, i.e
NB. script description...
Definitions produced by the script are documented in comments where the
first comment line begins NB.* and has the form:
NB.*name type description
where type is a single letter:
a adverb
c conjunction
n noun
v verb

Regarding scriptdoc here's a trick.
I have a document formatting tool (adapted from an APL program)
that neatly left and right justifies the text of comment blocks.
I applied this tool to all the comments in
the ODBC scripts and then ran the scriptdoc to display
the neatly formatted regions.
Scriptdoc picks the first letter of the second word encloses it
and encloses it in ()'s, eg:
NB.*word verb (becomes) NB.*word (v)
Note that the length of the first line changes. This wreaks
the neat justification. You can escape this dire fate by
simply appending two characters of your choice. I use:
NB.*wordname v--
which scriptdoc renders as
NB.*wordname (v)
preserving line length.
Also, the strings NB.* and v-- or a-- n-- c-- are sufficiently distinct
that it becomes very easy to pick out the names
between them.

Hi,
This facility allows you to browse the current locales and definitions
within each locale.
Download the file http://www.jsoftware.com/source/jnav.zip and unzip
into
your J directory:
pkunzip jnav -d -o
Then load the system as:
load 'user\projects\jnav\jnav.ijs'
The system can also be opened in Project Manager.
Alex
P.S. You have to have comctl.ocx installed on your computer.

There has been so much good stuff in the jforum lately:
Alex's navigator is a nifty J locale environment browser. I played
with it and was impressed. It looks very nice
and it makes it painless to poke around a J task.
I'd urge everyone to take a look and pound away we
need more tools like this. Slick work.
Here are some unsolicited observations -- the best kind:
I was running the browser on an NT/sp4 machine.
1) The browser does not see numbered locales (or
objects created with conew). Being able to look inside
numbered locales would be a big plus. As there is
no essential difference between numbered and named
locales (conl 0 for named) (conl 1 for numbered) this should
be a trivial enhancement.
2) There are some bugs to work out when clicking around
you can hit value errors. nav_ls_button is common. The error
message refers to TrackPopUpMenu_Locale_. It seems to be looking
for this utility verb in incorrect locations. One this happens youi
have to press the reload.
3) The layout of the various views can go wonky after value
errors.
4) reload does not clear all panels It would be better to clear
since the locale tree view is refreshed.

J doesn't provide this. I agree that facilities like this are
desireable.
There is a somewhat related facility in 4!:5 (see documention on
foreign). It might be worthwhile to take a look and see what could be
done with that.

There are two possible uses for this I can see:
1. To enable watchpoints during debugging; the actual variable name may
change depending on the nature of the error found.
2. To have the variable become a trigger; the actual variable name is well
defined.
For the first option, some enhancements to the debugging tools may be
needed.
For the second option in APL at least, I have a verb "is" which works as
follows:
'name' is value
is the same as
name <- value
After I change all occurences of the assignment to the "is" covered
assignment,
I can then insert a trigger based on the value of the name. Note that the
scoping rules of J allow only global assignments to be effectively set up
this
way.

I managed easily to build a connection to the server from my NT 4.0 machine
but could not establish the data connection - so I could connect
but could not download data.
(Eg. I got the message :425 Can't build data connection: Connection

So I think I should set up another session somehow to make it work.Does
anybody know how?

Are you aware that FTP uses different TCP connections for control and
transfer, respectively? Are you clashing against a firewall and would
better use PASV mode?
It's a bit difficult to give any more advice in response to your
question. It would be very helpful if you'd include a dozen
lines of J code you are using. (And, please, _not_ zipped or b64'ed.
There is a reason that J uses ASCII: to be readable as-is. Thanks.)

I am not sure where it comes from(definitely with VB or VC++ or Office97)
but you can get it from:
http://www.eu.microsoft.com/officedev/prodinfo/odeandvb.htm
copy comctl32.ocx to your windows/system directory and then run :
Regsvr32.exe comctl32.ocx

As far as I know comctl32.ocx is Windows only.

I never missed these triggers. For me, the time-honoured solution
substituting assignments with update procedures is just fine.
I programmed a tiny bit in LOOPS years ago. LOOPS is basically
a OO Lisp dialect with assignment triggers (and more). My overall
impressions were:
- Triggers can be nice in trivial settings.
- "Notify" style triggers which are "mostly readonly" are the most
useful ones but it's up to the discipline of the programmers where
to draw the line (A gets changed, B gets notified, actions "at B"
do not influence preceedings at A but are local to B. Hopefully.
Caveat debugger.)
- It doesn't scale to non-trivial settings. For example, when a bunch
of variables reflect a record, you get quickly to the following
problems in Real Life:
- How do can I block updates when serialized individual ones
are either performance-wise silly or ...
- ... desastrous because what you really need are guarantees about
"transactional updates"?
- How do you control cascading or even circulous triggers?
- The assignment as a side effect bears already enough potential
for causing headaches. Extending "=:" to cause potentially more
side effects beyond setting the mentioned variable turns code
walk-throughs into nightmares.
I stopped using LOOPS for the last reason. The "=:" vs. wrapper
distinction on the other hand is maybe old-fashioned but at least a
clear indication where Things May Happen and where not.
I also think that J's object locales provide a decent way to formulate
"set methods" for objects. [LOOPS was actually expressing triggers in
terms of "set" methods, too.]

I haven't had a chance yet to check out Oleg's zip file. But I
can certainly run all kinds of filters on what's there on juggle.
(For example, all the headers and footers are attached to the
bare page by some kind of filter. The file behind the url
http://juggle.gaertner.de/hitlist/hitlist is actually the
3-column raw data file -- associated with a filter.)
The CVS repository on juggle is already serving the entire official
J script library as it is used for the Unix platforms. (Chris
Burke just learned how to work with it and Unixers can already
check out the first few patches from it. Recent submitters
of J code on this this have just been contacted and invited
to file their stuff in the repository.)
The primary purpose of the J repository is to allow uploads and
downloads in a revision controlled manner. Updates are sooo much
easier for all involved parties, compared with .zip files.
As an additional feature and exploitation of the material there,
it should be no problem at all to run a "check out the newest
version and revamp it into html" on any script in there.
Voila: John's wish for the scripts "mounted in this formatted
form" is fullfilled.

Many years ago I set up a job that needed to pass data between machines and I
used J to create bat files with the FTP commands that were needed. It worked very
well and the last I heard it is still running without any problems nor changes.
I also had a very simple VB program to call mailbox and prepared the files
for it in J. Reading and using the files I received over mail or FTP to prepare
and create other files.
To make life simple I created several directories and used control files to pass
information between different processes and programs.
Sometimes simple solutions are ok.

I find your `Locale Browser' to be not only useful, but instructive
both in J matters and in Windown API matters.
To help me understand it in greater depth, could you point me to
some documentation of `olemethod' calls? I don't know the parameters
so some of the calls are a little hard to understand.
Thanks for making such a helpful piece of work available to us all.

My source of information about OLE calls are 2 .hlp(Comctl1.hlp Comctl2.hlp)
files that comes with VB or VC++. May be you can find those files on the
Web, but if you can't I can send it to you (330K zip archive). And you
should be aware that some OLE features are not supported by current J
implementation.

I have just added a program to My J Page at
http://www.cs.ualberta.ca/~smillie/Jpage.htm
for the minimization of a function with an arbitrary
number of variables. It is based on an algorithm
described in the paper �A simplex method for function
minimization� by J. A. Nelder and R. Mead, �The
Computer Journal�, vol. 7, 1965, pp. 308 - 313.
This algorithm has been previously implemented in J
and was referred to in a paper given at the J
Conference in Toronto in June, 1996. The author of the
paper was from the University of Wisconsin, but
unfortunately I have forgotten his name.

snobol has a code word taht allows a program to write a code string
and then execute it assembly language style.
It would be nice to write code of arrays that can evaluate a problem once
then execute an optimized version without further jump switch tables.

Thanks for trying, but this appears to give me a new COMCTL32.DLL
and still fails to document any of the calls supported by the .DLL.
At the moment I am trying to find documentation so that I can
understand the calls in JNAV.
I appreciate the attempts at help, but at the moment I'm afraid that
I'm `seeing thru a (windows) glass darkly'...

The most common example is that call to 'olemethod' can return a new object
which you can not use in your J program(example: for the ListView control if
you want to add more then one column in 'detail view' you should call OLE
method which returns you a new object, representing this new column)
Another example: I can enable certain event but can not disable it back.
And OLEDrop event returns object of 'Unsupported type' (I was thinking about
dragging scripts from Windows Explorer to JNavigator but I could not
implement that because of this problem :-( )

I agree with M.Neitzel that trigger-based programming does not scale.
However triggers are very useful on a small scale and I hope J will
acquire them at some point. How difficult would it be to implement,
really? (I have no idea).

I just encountered Blackwell's `IdeaList'. It seems, at first
glance, to be a rather nice Text/Tab Card storage/recall system.
Has anyone developed this kind of support technology in `J'? I feel
that I am too much of a novice to do it, but the capabilities
sure seem to be something that J could deliver with ease if one
was comfortable enough with J to do a fast implementation.
I also have the hunch that J code to perform functions of this kind
might serve a valuable tutorial function to expose aspects of J
that are quite different from the more usual computationally
directed examples.

Not i, though it is inherently interesting to me. i would
think an important step would be an XML interface. The hashed
& aproximate match retrieval aspects interest me most. And
would benefit most from J. Could have wide relevance, eg to
BioInformatics.
Has anyone tried hooking J to Perl? Would give one access to
the Perl-XML modules. i believe ActiveState has mechanisms
for exposing Perl at a pretty basic level. O/w there are
Java XML tools too, eg from the IBM Skunkworks.

I am currently doing some work with ActiveState's PERL. I will keep
J in mind as a wander thru this thicket, but my most rewarding
stuff so far has been on the PERL-Tk interface, which seems to work
quite well (and which is described in considerable detail in O'Reilly's
`Perl/Tk' book).
Many of the advantages of J's Windows interface seem to be easily
available in PERL-Tk as well, so it is not clear to me that J really
has a lot to _add_ to the Perl/Tk combination. In a week or so, maybe
I'll have done enough work to know better.

Some Unix maven will have to comment on Tk/Unix. Perl/Unix is surely
a commonplace. I would have suspected that there is an `X' version
of Tk, but I don't actually know.
Perl is pretty good at indexing, though. And I remember running a
benchmark of Perl regular expression stuff against J, and my Perl
was much faster than my J. Of course, I am probably a better Perl
programmer than J programmer, so that comparison might not have been
valid.

The HP Jornada (HPJ) family seems to comprise 3 products: the existing 1.1
kg HPJ820 (Intel StrongARM cpu)handheld PC, and the newly-announced 0.51 kg
HPJ 680 (Hitachi SH3 processor) handheld PC and the 0.250kg HPJ420 (Hitachi
SH7709a processor)palm-sized PC. Presumably, J for Windows CE runs on the
Hitachi-based 680 and 420 but not the StrongARM-based 820.
The 680 has a keyboard which is 76% the size of a normal keyboard, 16MB RAM
upgradeable to 32MB, 640x480x256 color screen resolution. Looks like a
machine that can be used for substantial J code development.
The 420 is a palm-type device without a physical keyboard but having a
"one-screen keboard" which is acessible through a stylus/touch. It has 8MB
RAM and 240x320x256 colors screen resolution. The J for WinCE press release
last December mentioned that:
"For best results, 16mb or more is recommended. J can run on a smaller
machine, and indeed runs nicely on a machine with only 4mb, but may not have
enough room for all the demos and labs, and may allow only very small apps."
The 420 thus might allow testing of code fragments but might not be
well-suited for larger-scale applications.
Those with actual experience in using J on Wince might be in a better
position to comment on the suitability of the new HPJ machines. I was hoping
that J would be made available for the 820. If not, I suppose I will get a
620 when it becomes available outside the US in May.

Actually it can be outfitted with 10 more M by using the FlashCard slot.
That's still not a lot but the other models are too expensive for what
they are, IMO.
I would like J Software to confirm that the SH7709a Hitachi processor
is OK: their web page only mentions the SH3.

I have for some time been using various methods for interpolating sparse
data in a 2 dimensional array. Typically data could be 'air or water samples
across a geographic area' normally displayed as an image.
With the current availability in J of the FFTW, I was interested to see if
use could be made of this process for my purpose. I had in mind making the
transform, filtering the data possibly as an image to try and remove the
'blanks' and finally to invert the results.
Are there any brave souls out there who would like to comment on the concept
or feasibility of such a plan. Any ideas on what type of 'blank padding' and
filter might be suitable or worth trying.
Must confess that my efforts to date have not born fruit.

A start might be to triangulate the area with some
minimizing criteria like Delaunay triangulation then
improve the linear interpolation using some splining
mechanism, eg B-splines or wavelets.

i would expect a lot of ringing from a global method

The following extract from a Q&A at the Hitachi website confirms that the
SH7709 chip used on the HP Jornada 420 is in the "SH3" family. It should
therefore be possible for J for WinCE to run on the 420?
"Q: Which Hitachi processors run Windows CE?
A: - Hitachi offers three today, all in the SH-3 series � SH7708, SH7707,
SH7709 - More SH-3 and higher CPUs will come out soon - At least two of the
SH-3 CPUs (SH7708, SH7709) will offer performance upgrades to 100 MHz and
higher"

Thanks Greg;
I am aware of several more conventional methods of achieving the
interpolated results;
I was just interested to see if there was some interesting ideas from the J

I wish to place a multiple line text in a grid cell. How do I do this? How
do I separate the lines?
I tried the lab as a starting point, expecting to enter multiple lines and
then read the cell to see what is in there.
In the lab it says: "You can use Alt+Enter to enter multiple lines in an
edit box"
It didn't work. Since I couldn't enter it, I couldn't read it. I tried
separating lines by 10{a. or 13{a but no success.

Adverbs have to go after the modified term. You could have:
taylor4 =. 1 : 'u. t. 0 1 2 3 4'
*: taylor4
0 0 1 0 0
I was unable to figure out a way to do this tacitly, and I'd
like to see somebody do it.
In (vec1 b vec2), b is a conjunction (as is your R), and
you can simply use
b =. R taylor4
2 2 2 b 3 3 3
0.666667 0 0 0 0

This is a bug.
Right now, multiple line text requires that the cell be left-justified (1 in
col 10 of the attribute matrix). If so, you can use LF as the line
separator.

I have put 2 grids (2 isigraph objects) on a single form and everything
worked. I could control events and data on each grid separately from
the other. This included resizing the grids. The only problem I ran
into is I couldn't get a gotfocus or lostfocus event for each isigraph
object so I could change the color or highlight the grid which had
focus.
This may be different in that you want a graph and a grid on the same
isigraph object. Don't know about that.
Let me know if you want information on what I did.

Is there any chance that a stripped-down version of J could be ported to the Palm
Pilot? (I recently purchased a PalmV). I know that the PalmOS has a weird
development environment, and that the WinCE devices are much easier to port to
(because Microsoft made CE a subset of normal Windows). However, there are many
times more Palm Pilot users (in the millions) than the nearest WinCE competitor, and
CE is sluggish and complex compaired to PalmOS. For every Jornada there are 1000
Palm Pilots. I carry my Palm V with me everywhere (its much thinner than the old
Palm III or any of the other palmtops) and all it has for computation is a crumby
touch-pad calculator. The terseness of J is perfect for a pen-entered device with no
keyboard, and I would be able to solve complex problems anywhere, without having to
drag my laptop along.
You could beam your latest algorithms and programs to your co-workers and friends.
Imagine shipping everybody Pousse via IR. Imagine building multi-user games using
the IR port as a network! You could write J programs in Win98 and sync/download them
to the Pilot (and vice-versa). "PilotJ" could become the next "hot thing" for the
discriminating Pilot user! The Palm V only has 2 Meg of memory, so I would expect
that you would have to leave off some of the more esoteric J functions. However,
just the basic set of verbs would put my Pilot in a new orbit... ;-)

Does the Palm Pilot run Dos programs? If so the old public domain version

find it very useful. I have not switched to a Palm Pilot primarily because
I did not know if it could run J.

No. It doesn't. I don't know if the state of DOS emulators has
changed since I looked about a year ago, but there wasn't anything
useful then, and the Palm was bad enough that I gave it away and
therefore haven't looked since.
I also regularly use J on my 200Lx.

A few months ago some one posted the URL
of a very good survey of programming
languages. I would appreciate some one sending
me the reference again.
Thanks a lot.

I think it was on the J archive. It is listed (due to an old numbering
sequence for versions) as 6.2. I was certainly public domain, and
there was source for V7, but I never bothered trying to compile it.
J6.2 works fine, but is (needless to say) quite limited in comparison
with current day `J'. J is, however, such a `good idea' that even this
relatively crude implementation is quite useful.
If you have trouble finding it, let me know.

Subject: Re: Jforum: graphs and grids on form

Don,
Mostly I want grids & graphs for making changes in a table & displaying
results--interactively or on button command. Hope the focus defect doesn't
apply in this case.
What I need is a script (or parts thereof) that contains the creation and
placement of a grid, a graph, and a normal form object or two such as a
button or list.
I'm pretty experienced building forms using J, but this J-oop stuff is new &
strange. My previous stab at grid/graph didn't work because (maybe) I tried
to create the graph normally when it might have to be done as an object.
Once I see how to get things started, I should probably be okay.
Thanks for the help.
Donald Pittenger

If I understand you correctly you shouldn't have any problem. You want two isigraph
objects on your form, one a grid and the other a graph. The grid receives input but
the graph is output only. Is that correct?
My problem with the focus was that I couldn't give the user a visual indication as
to which object had the current focus. Internally the program worked fine. Regular
form objects automatically change their look when they recive and lose focus. It
wasn't a problem if I used the mouse to switch objects - I get an event. But I
wanted to run it from the keyboard also. Tabbing from one form object to the next
does not generate an event. Normal objects automatically change their appearance.
Isigraphs do not.

objects on your form, one a grid and the other a graph. The grid receives input but
the graph is output only. Is that correct?
My problem with the focus was that I couldn't always give the user a visual
indication as to which object had the current focus. Internally the program worked
fine. It wasn't a problem if I used the mouse to switch objects - I get an event.
But I wanted to run it from the keyboard also. Tabbing from one form object to the
next does not generate an event. Normal objects automatically change their
appearance. Isigraphs do not.
You should be able to do both on one form with or without using objects. It's just
that using objects really simplifies things. It just doesn't seem to at first. You
have to keep in mind are that events occur in the locale of the form. You have to
pass events from the form's locale to your user object. Second, the name space
switches when you are in your object. You have to do something to pass data from
the form's locale to your object's locale. If it's only one or a few names, you can
pass them as arguments. If you want to refer to a lot of names just pass the name
of the form's locale and refer to them indirectly.
Of course, you could avoid the whole problem by displaying the graph in a different
form. Then event handling will be simpler. The nice thing about that is that the
user can resize and position things as he chooses. Quite useful on small monitors.
You could use the plot script if the graphs it generates are adequate.

The best place to get source, binaries and other material for old
versions of J is the Waterloo archive:
ftp://archive.uwaterloo.ca/languages/j/
An earlier message used the phrase 'public domain'. That phrase implies
no copyright or license and is incorrect with respect to J.
All J material is copyright by Iverson Software Inc. and its use is

available at no cost and has few restrictions on its use under the
license does not mean it is 'publice domain'.

Sorry, Eric. I think I said `public domain' when I should have
said something more like `available for use free of charge...'
Thanks for correcting the record...
