REDISTRIBUTION PERMITTED
Please distribute Davex widely! Permission is hereby
granted for Davex to be uploaded to electronic bulletin
board systems. It may also included in user group libraries
and other collections of Shareware, PROVIDED THAT NO MORE
THAN $5.OO IS CHARGED FOR ANY DISK CONTAINING DAVEX, unless
special arrangements are made with DAL Systems in advance.
MODIFIED COPIES OF DAVEX SHALL NOT BE REDISTRIBUTED, and
THIS DOCUMENT AND THE ONLINE HELP SHALL BE INCLUDED WHENEVER
DAVEX IS REDISTRIBUTED.
Davex can be licensed for inclusion with your own programs;
contact DAL Systems for details.
DAVEX ON MULTIPLE COMPUTERS: You should pay $25 for every
copy of Davex that could be in use at the same time, up to a
maximum of $200 for all computers owned by one company (or
school district). For example, several people using Davex
on one machine (or one person using Davex on several
machines in different places) should pay only $25; but two
people on two machines should pay $50.
COMMENTS AND SUGGESTIONS ARE WELCOME
DAL Systems will do its best to correct bugs and make
updates available. Davex is a continually evolving package,
and you can help shape its future. (Once you send in $25,
you are entitled to use later versions without sending in
more money. However, updates ordered directly from DAL
Systems will cost $3.)
KICKBACKS TO ENCOURAGE WIDER DISTRIBUTION
Starting with Davex v1.2
As a registered Davex user, you will receive a $5.OO
"kickback" for every new user who registers a copy Davex
containing your serial number.
Your serial number is the same as your registration number.
To put your serial number on your copy of Davex (if it isn't
already there, or if you get an update from a bulletin
board), use the "filetype" command to change the auxiliary
type of Davex:
filetype %davex sys -x99 [use your serial #, not 99]
Then type "$" to make sure it worked.
INTRODUCTION
Davex is a command shell for ProDOS. ProDOS has no way to accept
commands from you directly, so some sort of command interpreter
is required. Davex includes a large number of "housekeeping"
commands for managing your disks, directories, and files.
Davex is also a starting place for using other ProDOS programs.
When you run another program from Davex (just by typing its
name), you will normally be returned automatically to Davex when
you Quit the other program.
Note: This document is not a ProDOS tutorial. Please refer to
reference manuals or other introductory ProDOS texts for
explanations of ProDOS basics like volume, file, pathname,
directory, prefix, and filetype.
HARDWARE REQUIREMENTS
Any Apple II system that can run ProDOS and display lower case
can run Davex. Davex will be much more convenient for you if you
have at least one of the following: a hard drive, a large RAM
drive, two 5.25 inch drives, or at least one 3.5 inch drive.
Davex has been tested extensively on a variety of hardware. If
you find that your hardware is not supported, contact me to see
what can be done, or whether an updated version is already
available to support your hardware.
OPTIONAL HARDWARE
Davex supports the Echo II and SlotBuster II speech synthesizers,
using the TEXTALKER or SCAT software that you should already have
if you own one of these boards. To use TEXTALKER, just put a
copy of PT.OBJ in the same directory as Davex. PT.OBJ is part of
the Textalker software which has been licensed from Street
Electronics Corporation, the designers of the Echo, for
distribution with Davex.
For the SlotBuster, ProSCAT must already be installed; Davex will
recognize it but will not install it.
(Note to SlotBuster users: SCAT support is currently flawed.
Use "config -4y" to force a 40-column display, or "review" will
be garbled.)
FILES NEEDED FOR DAVEX
When you install Davex on a hard disk or RAM disk, you should
create a subdirectory for Davex. The name of the subdirectory
doesn't matter, but "DAVEX" is the obvious choice. From within
Davex, this directory's name can always be abbreviated as "%".
Davex itself is a SYS file in the % directory and is usually
called DAVEX, although the name does not matter to Davex.
%CONFIG is a BIN file; it stores configuration options like
printer slot, your scan list, and a file type table. %HELP is a
directory containing help files for individual commands. If you
are short on disk space, you may want to leave %HELP off of your
work disk. If you do, the "help" command will report "directory
not found" when you ask for help on a specific command. (You can
also put the help directory on another disk; use the 'config'
command to tell Davex the pathname of your help directory.)
No other files are required in the % directory. Typically there
will be external commands (BIN files) and SYS files there. If
you are using any aliases, there will be a TXT file called
"aliases" in your % directory (see "help alias"). If you are
using the Echo speech synthesizer, there should also be a copy of
PT.OBJ in the % directory.
RECOMMENDED HARD DRIVE SETUP
Copy the entire "%" directory onto your hard drive. Then, if you
want your system to to boot up directly into Davex, use the
"sysalias" command (try "help sysalias") to create a one-block
SYS program, with a name ending in ".SYSTEM", in your top-level
directory.
For example:
copy % /hard1/davex
sysalias /hard1/davex/davex /hard1/davex.system
(If there are other ".SYSTEM" files earlier in the directory than
davex.system, copy the first one to another disk, delete it,
create davex.system using the 'sysalias' command, and finally
copy the ".SYSTEM" file back onto the disk. This way,
davex.system will be the first program ProDOS sees when it looks
for a program to run.)
RAM DISKS
If your RAM disk is backed up by a battery, the instructions for
hard disks apply to you. Just install it once, and you're all
set.
To set up a disk that will copy Davex to the RAM disk and execute
it there, first you need to understand the "copy" and "exec"
commands. If there is a %autoexec file, it will be executed
automatically when you boot Davex. A typical %autoexec file
contains something like this:
copy %=:sys /ram/davex
copy %=:bin /ram/davex
copy %aliases /ram/davex
copy %help /ram/davex/help
/ram/davex/davex
The first line copies all SYS files from the % directory to the
RAM disk, and the second line copies BIN files. The third line
copies the help directory (if you have a small RAM disk, you may
not want to copy the help). The last line simply runs the copy
of Davex from the RAM disk.
(Note that it would be simpler to just "copy % /ram/davex". But
this is a problem because the %autoexec file will be in use,
causing the copy to fail.)
Once you are running the copy of Davex from the RAM disk, your
"%" directory is "/ram/davex".
APPLE IIGS USERS
See your dealer for the most recent version of the System Disk.
The most recent version (as of February, 1988) is 3.1. Davex
will work with older versions, but keeping up to date is always a
good idea for maximum compatibility with new software.
If you have an Apple IIgs and wish to have your system boot into
Davex through ProDOS 16 (so you can run S16 and EXE programs
without rebooting), the above instructions still apply to you.
You will also need to delete or rename the START file in your
SYSTEM directory. This will force the ProDOS loader to scan your
root directory for a startup application instead of running START
(which just runs Finder or Launcher). You may want to type
scan -a /your.boot.disk/system
so that you can run FINDER and LAUNCHER (in the SYSTEM directory)
just by typing their names.
USING DAVEX
When you enter Davex, you see (in 80 columns if your system
supports it):
Davex vX.XX (Serial #xxx)
Type ? for help, $ for ShareWare notice.
current_date_and_time
prefix:
Your current ProDOS prefix (the directory you're "in"), followed
by a colon (:), is your prompt. Davex expects you to type a
command and press RETURN. (If you press RETURN without typing
anything, you just get the current date and time and another
prompt.) [You can use the 'setdate' command to set the date and
time if your machine doesn't have a clock.]
Some commands can be executed just by typing their names. For
example:
help
online
quit
Other commands require additional information (called
"parameters") after the command name. You must type at least one
blank space between a command name and the parameters that follow
it. Examples:
delete that.file
lock /disk3/standard.ltr
For some commands, parameters are optional.
help
help copy
info
info /my.disk/my.file
You may put more than one command on a line if you separate the
commands with semicolons (;). If an error occurs during one
command, the remaining commands will not be executed.
WHAT IS A COMMAND?
There are three kinds of commands:
1. built-in commands
Built-in commands are part of Davex and are always
available. When you type a command, Davex always checks
first to see if it's an internal command. (The '?' or
'help' command displays a list of all internal commands.)
If the command you typed is not internal, it looks on your
disks, trying to find a file with the same name. You can
tell Davex what directories to look in by using the 'scan'
command. (See "help scan".)
2. external commands
If the non-internal command is found to be a BIN file, Davex
attempts to execute the file's contents as an external
command. These files are usually found in the same
directory as Davex, although they can be in any directory on
your scan list.
Davex features such as wildcards and shorthand pathnames are
available with external commands.
A few external commands are supplied with Davex; an appendix
describes how assembly language programmers can write more
external commands.
3. SYS, S16, and EXE programs
If a non-internal command is found to be a SYS or S16
program, Davex runs the program. When you quit the other
program, you will be automatically returned to Davex.
[You need the file BRIDGE.S16 in the same directory as Davex
to run S16 and EXE programs directly from Davex. These work
only on the Apple IIgs, and you need to boot through
ProDOS 16 to run them.]
SHORTHAND FOR PATHNAMES
'%' is shorthand for the name of the directory Davex is in. A
'/' after the '%' is optional. Examples:
cat %
cat %help
cat %/help
info %davex
You can specify a volume by slot and drive number like this:
info .61/prodos <==> info /xxx/prodos, where /xxx is the
name of the ProDOS volume in slot 6,
drive 1
prefix .32 <==> prefix /xxx, where /xxx is the name of
the ProDOS volume in slot 3, drive 2
(usually /RAM)
WILDCARDS
It is often convenient to execute one command (for example,
delete, lock, or copy) on a group of files all at once, rather
than on one file at a time. Davex provides wildcards as a
convenient way to work with groups of files.
'=' and '?' are wildcard characters; they "match" any number of
characters in a file's name. You can use wildcards in the last
segment of pathnames for many commands. Only one wildcard per
pathname is permitted.
Examples:
lock = Locks all files in the current directory
delete =.old Deletes all files ending in ".old" from the
current directory
'?' is like '=', but Davex asks you whether or not to operate on
each matching file. Examples:
lock ? For each file in the current directory, asks you
"lock xxxxx? (Y/N)". Type Y to lock the file,
or N to skip to the next one.
delete ?.old For each file in the current directory whose
name ends in ".old", asks whether or not to
delete it.
You can restrict a wildcard to match files only if they are of a
particular type. Examples:
pg part?:txt For each "txt" file in the current directory
beginning with "part", ask whether or not to
"pg" the file ("pg" displays a file one
screenful at a time)
ALIASES (ABBREVIATIONS)
Starting with Davex 1.2, there is a primitive "alias" mechanism
available. Before Davex tries to find your commands (in the
built-in list, or on disk), it first checks your aliases. If
there is an alias for a command word you typed, Davex replaces
the word with what it stands for, and continues process the
command line.
Type "alias" to see what aliases are defined.
The aliases are stored in the TXT file %aliases. See Appendix C
for an explanation of the aliases that come on the disk as
shipped from DAL Systems. (Of course, you can change the
supplied aliases and add your own--just edit the %aliases file
with a text editor.)
Note: If you use wildcards with an alias, you may be surprised
to see Davex refer to the command by its real name. For example:
/my.disk: kill a?
delete /my.disk/apple? (y/n)
delete /my.disk/apricot? (y/n)
(Davex's alias mechanism does not currently support parameters.
If it did, the 'move' command would simply have been implemented
as the alias "move copy #1 #2 -d", for example.)
PAUSING AND ABORTING
If you press SPACE while the screen is scrolling, it will freeze.
Each SPACE press will generally advance the display by one line.
Press RETURN to continue scrolling.
Ctrl-C or Apple-period will print "*** aborted" and will always
return you to the command line prompt.
ESC aborts the current operation, but does not necessarily return
you to command level. For example, if you are executing "pg =",
ESC will abort paging the current file, but pg will begin
executing on the next file matching the wildcard.
CONTROL CHARACTERS AVAILABLE WHILE TYPING A COMMAND LINE
(from "help cmdline")
Ctrl-B = move to beginning of line
Ctrl-D = delete character at cursor
Ctrl-E/Ctrl-N = move to end of line
Ctrl-F = find forward; press ESC to exit
Ctrl-H (left arrow) = move left
Ctrl-I = insert (cancelled by arrows or Ctrl-D)
Ctrl-J (down arrow) = move down on the list of previous
commands
Ctrl-K (up arrow) = move up on the list of previous commands
Ctrl-L = toggle Caps-lock on/off for Apple II+
Ctrl-M = return (accept whole line, even the part after the
cursor)
Ctrl-O = if the following character is a control character,
inserts it (control characters can't normally be
entered). If the following character is "K" to "O"
or "k" to "o", a special character is inserted
(useful only on the II+ keyboard):
K L M N O k l m n o
[ \ ] ^ _ { | } ~ DEL
Ctrl-Q = accept portion of line before cursor
Ctrl-R = re-edit previous input
Ctrl-U (right arrow) = move cursor right
Ctrl-X = cancel input
Ctrl-Y = erase from cursor to end of line
DELETE = erase character to left of cursor
Apple-Y = same as Ctrl-Y
Apple-H = Hardcopy of screen (set printer slot with config)
(beeps twice if priner is busy) [doesn't work on
the Apple II+]
MUCH MORE INFORMATION ONLINE
This document is intentionally short. Information on each
command and on other topics can be found using the 'help'
command. Type 'help help' (or '??') to get started.
The first line of each help file shows alternative names for the
command, if there are any. Then the command's syntax is given,
using square brackets around the parts you can leave out.
DON'T IGNORE THE ONLINE HELP! Even if a command's purpose and
use seem obvious, take a quick look at the help. Most of the
commands have handy options that you won't know about if you skip
the help.
"DASH" PARAMETERS
Many commands take optional parameters following a "-". A letter
identifying the parameter follows the "-". In some cases, a
value (a number, or string, for example) is expected after the
letter, and in other cases nothing more is required.
Examples
cat /xyz -t The "-t" stands for "tree"; when a DIR
appears in the listing, "-t" tells the
catalog command to indent two spaces and
list the contents of the directory. No
value is expected after the "-t".
cat /x -fsys The "-f" stands for "filetype"; a filetype
must be specified after the "f". (In this
example, files not of type SYS will not
appear in the listing.)
Internal commands
This is just a list of commands. It tells you what commands are built
into Davex, but it does not explain them. Consult the online help to
find out how to use a specific command.

External commands
These commands are supplied with Davex. Other external commands can
be written by an assembly language programmer.
blist list a BAS file in ASCII
brun run a BIN file ['brun' is actually a small SYS
file, not an external command]
chkmod compare modification dates on pairs of files
conp set IIgs control panel options
deschw describe system hardware
du summarize disk usage
ffind search directories or volumes for files (find by
name, type, auxiliary type, need-backup)
find search files for lines containing a given string
gsbuff set Apple IIgs printer/modem buffer sizes
hdr print lines from the beginning of a file
init initialize (format) any ProDOS block device (or
just write Boot blocks to a volume)
iw2 set up print options for ImageWriter II
mx80 set up print options for Epson MX80
pset set up print options for NEC8023 / ProWriter /
Imagewriter
setdate sets date and time (only if no clock available)
setstart examine or set the startup path of a SYS
application
sysalias create an alias for a SYS file
what determine what a file is (this can be really
handy!)
TRICKINESS
If a non-internal command is found to be of type DIR
(subdirectory or volume), Davex simply sets your prefix to that
directory. This is similar to using the 'prefix' command, except that
the scan list is used.
After an optional parameter that accepts no parameter value,
additional parameters can follow without another "-". For example,
copy this that -fb
is the same as
copy this that -f -b
and
cat .61 -ta
is the same as
cat .61 -t -a
HOWEVER,
cat .61 -at
is NOT the same as
cat .61 -a -t
because the "-a" parameter takes a string value (in "cat .61 -ta" the
string value following "-a" consists of 0 characters).
Some SYS files can take a pathname parameter; BASIC.SYSTEM, for
example, will run whatever BAS file you specify as its parameter
(actually it does a '-' command, so you can also BRUN a BIN file, EXEC
a TXT file, or launch a SYS file). If BASIC.SYSTEM is available in
one of your scan directories, you can type
BASIC.SYSTEM MYPROGRAM
to run MYPROGRAM under BASIC.SYSTEM. To Davex, the parameter
following the name of a SYS file is a STRING, not a pathname. This
means you can't use the "%" or ".xx" shorthand notations in the
parameter.
(Note that BASIC.SYSTEM does not always preserve your prefix. If your
prefix refers to a subdirectory, BASIC.SYSTEM will preserve it;
otherwise it sets the prefix to be EMPTY and behaves like DOS 3.3--it
goes by slot and drive numbers and defaults to the slot/drive that
BASIC.SYSTEM was loaded from.)
The 'info' command will tell you whether a particular SYS file has a
startup buffer.
Appendix A: Hardware Compatibility
Davex has been tested with the following Apple IIs: Apple II+
(SmarTerm 80-column, shift-key mod), Apple //e (original and
enhanced), Apple //c (original and UniDisk 3.5 ROM), and Apple IIgs.
IIgs Support
Davex is compatible with the IIgs but does not behave much differently
than on an eariler Apple. Since Davex does not disable interrupts,
you can use Classic Desk Accessories (including the Control Panel)
with no problem. If you launch Davex from a ProDOS 16 controlling
program (like the Launcher, APW, or ECP16), you will be returned to it
when you quit Davex. You can launch a ProDOS 16 application (a file
with type S16) by typing its name (assuming the directory it's in is
in your scan list), and you be automatically returned to Davex when
you quit. (The file %BRIDGE.S16 is a tiny ProDOS 16 application that
makes this possible.)
Appendix B: AppleWorks Compatibility
The pg and type commands recognize AWP files. In future Davex
versions, 'spool' and 'exec' will probably recognize AWP files.
The 'cat' command displays AWP, ADB, and ASP filenames using the
capitalization you used when naming the files in AppleWorks. (This
information is stored in the files' auxiliary type fields.)
Appendix C: Standard Aliases
This appendix lists and explains the aliases provided in the
"%aliases" file. You can use a text editor to remove or change these
aliases, and you can add your own. The maximum size of the %aliases
file is currently 512 bytes (one block); if your %aliases file is
longer than 512 bytes, Davex simply ignores the excess.
q bye
quit q
Explanation: "q" and "quit" stand for "bye" (leave Davex).
> como
< exec
Explanation: ">" stands for "como" (send output to a file or slot)
and "<" stands for "exec" (get command input from a file)
cd prefix
pfx cd
down cd
Explanation: "cd" (change directory), "pfx", and "down" all stand
for "prefix". "down" is appropriate because the 'prefix' command
takes you down to a subdirectory if you use a partial pathname
(example: "down mydir" or "down firstdir/xyz/abc").
\ up
Explanation: "\" stands for "up", which takes you to the directory
above.
over up;down
Explanation: "over" stands for "up" followed by the directory name
you type. Example: If your prefix is "/mydisk/dir1" and you type
"over dir2", your prefix will then be "/mydisk/dir2". Wildcards are
allowed, because they are not expanded until the "prefix" ("down")
command is executed.
or %;top
origin or
Explanation: "origin" or "or" takes you to the top level directory
of the disk Davex is running from. "%" takes you to the Davex
directory, and then "top" takes you to the top level directory.
o online
Explanation: "o" stands for "online", which shows a list of all
disks in your drives.
home cls
Explanation: "home" stands for "cls", which clears the screen (or
starts a new page on the printer).
slist type
tlist type
Explanation: "slist" and "tlist" stand for "type", which displays
the contents of a file.
more pg
Explanation: "more" stands for "pg", which displays the contents of
a file one screenful at a time.
mv rename
cname mv
Explanation: "mv" (move) and "cname" (change name) stand for
"rename", which changes the name of a file, directory, or volume.
ctype filetype
Explanation: "ctype" stands for "filetype", which is used for
changing the type or auxiliary type of a file.
mkdir create
md create
Explanation: "mkdir" and "md" (make directory) stand for "create",
which can be used to create subdirectories (as well as other files).
rm delete
del rm
kill rm
Explanation: "rm", "del", and "kill" all stand for "delete", which
erases files and directories.
catalog cat
dir cat
ld cat
ls cat
Explanation: "catalog", "dir" (directory), "ld" (list directory),
and "ls" (list) all stand for "cat", which displays catalog
listings.
cp copy
Explanation: "cp" stands for "copy", which copies files and
directories.
e echo
Explanation: "e" stands for "echo", which prints the strings you
feed it (useful from "exec" files).
ej eject
Explanation: "ej" stands for "eject", which ejects 3.5" disks from
their drives.
print > &;
Explanation: "print" stands for redirecting output to the printer,
and the semicolon between commands is included in the alias, so you
don't need to type one when you use it. Example: "print help
rename", or "print cat -t", but NOT "print filename".
page > &;cls
Explanation: "page" does a clear-screen after sending output to the
printer. Result: the printer advances to the top of the page.
