Hardware / Re: Is it possible? OS/2 for Power PC in Action on Cebit 95?
« on: October 10, 2021, 12:59:28 pm »
I had a look through OS/2 PPC to see what it was made of.

The DOS is based on PC-DOS 6,30, and has REXX installed as well.  There is a help command, which functions as the PC-DOS 7 help, but loads the OS/2 CMDREF instead.  Although the rexx is similar to the PC-DOS 7 rexx, will not run rexx.bat scripts like in 7.0 and 7.1.  Unlike the intel version of OS/2, the DOS is pretty complete.  It's in the various reviews I write on DOS as PC-DOS 6.32.  (see )

The wallpapers are similar to the 3.0 set, but there are some 4.0 features in there, which is why I group it under 3.5 (3.1 is a version number i had reported by tcmdos2 under Warp Connect 3.) 

OS2 PPC does indeed look like 3.0, iconwise, but since all the books on OS/2 Warp is 3.0 stuff, i see that even OS/2 4 server reverted to the 3.0 icons.

OS/2 shipped some wallpaper that was OS/2 tiles.

v3.00 os2tile.bmp is a relief-grey version of the tilted square.
v1.30 os2logo.bmp had a full size neon logo.
v3.00 os2logo.bmp had the non-wavy OS/2 Warp under the tilted square.
v4.00 os2logo.bmp is a small square tile of the standing up version of the rings.
v3.50 had a wallpaper for OS/2 PPC.  (3.50 is OS/2 ppc)

Programming / REXX under OS/2 etc
« on: October 10, 2021, 11:22:22 am »
My first exposure to REXX was Quercus Personal REXX for DOS in 1993.  Anyone who has looked at Richard Goran's guide to REXX, or played around with REXXLIB.DLL, would have encountered it.  In its day, it was the fastest one going, because it tokenised everything after the control-Z.

It came in flavours for DOS, OS/2, Windows 3.x and 95/NT.  Of course, we were managing things like 4DOS and 4OS2 back then, on a freshly minted OS/2 2.10.

The language was somewhat more versitile than other languages like BASICA, in that it was more 'open' to the OS.  You could for example, edit binary files, and make decisions on what part(s) of the binary to edit.  Back in the day, I was collecting operating systems as they hit the deck. 

Quercus REXX is the only rexx that I replaced OS/2 rexx with.  Some programs did not like it (eg GearOS2), but because of limited memory and such, Gear (a cdrom burning proggie), was run in an OS/2 PM session, with filebar as the shell.

Looking at the feature-set, Quercus is closest to Regina, except that it is not ANSI complient (no changestr), but was getting sufficiently close to OS/2 that they were advising people to use the OS/2 functions where appropriate.  Some of IBM's commands were slightly supperior (eg FILESPEC, DIRECTORY).

Some of the early AI stuff (like renaming OS/2 icons and attaching help pages through the MINDEX object), were done in this.  Using Norton Utilities 'InstDOS', thing, one can create whole Windows/WinOS2 desktops through rexx.  I still do it that way.

PC-DOS 7  had a version of REXX for DOS.  It caused a few headaches with 4DOS, because it used REXX ,BAT scripts.

When the 486 finally died in 2002, I moved across to Windows 98, Windows 2000, and finally (last year), Vista 6.1.  None of these had REXX, but you could coax regina or even quercus to run in these environments.

4NT will see and use rexx .cmd programs, but i normally pass these through as .rex scripts.

Regina Rexx is about the only ANSI level REXX (non-OO), and being on DOS, OS/2 and NT, is pretty versitile passing batches through.  The recently posted RXLOOP.REX works just as well under OS/2 as under NT (where it was written)
All of the rexx scripts handle bignum.  Have a look at and my fibonacci series calculator (it's the world record, written under rexx).

This is the sort of utility i use in AI's,  It's a distribution of keys before or after the progs are installed.

This is the output batch.

Code: [Select]
@echo off
echo key for Zippy
copy zippy.key c:\programs\zippy

The second !loop command says which letters to process.  These can be anything, but because we only wanted to move the zippy.key to its proper place, we used only 'r' here.

Code: [Select]
extproc regina.exe rxloop.rex


$data $nkp
r,Zippy    ,zippy.key,$P\zippy
g,GSview   ,gvpm.ini,$S,
g,Dragtext ,drgtxt39.ini,$P\drgtxt39
g,Amipro   ,amiuser3.ini,$S
g,Lotus SS ,suit.ri,$L

$new distkey.cmd
@echo off
$loop *
echo key for $n
copy $k $p
$loop r

This is RxLoop.  We run it under Regina. rather than SAA, because the former is ANSI complient, and can be run as an application.  You see it's woven from zloop.cmd.  Looking at this shows the specs as implemented for the program, and the bits and pieces of proggie in random order.  At some point, we pull the bits together and make rxloop.rex,

Utilities / Re: MeShell commandline frontend timetable
« on: October 09, 2021, 11:38:59 am »
It looks from the screen layout of MeShell that it's going to be a permanent thing, so it's best to include this sort of stuff in the help file (see eg searchplus for an example).  See picture from searchplus.hlp refering to dragtext39. 

The same bug exists with MeEditor.


If you run console applications (like fc/2 or q edit), they hide in the invisible console.  This has a button up the top, so that maybe it could show the name of the running program.  A reference to this in the install.txt might help too.

Applications / Re: Accelerated Installs

Most of the installs are handled by rexx scripts or batch files after the files are copied.

Service packs are integrated if the install consists of loose files.  Nothing is done to packages, either pack2 or wpi. 

There is some 'copy over' stuff.  For example, \os2\mdos\ is copied over with a functional one.  Qbasic.exe is updated to the final IBM release of this.  The ones in 5.02 and the update are later than the OS/2 one, which is the first of the non-linked versions.

When you modify the DOS path from c:\os2;c:\os2\mdos;... to c:\os2\mdos;c:\os2;  you can install the DOS E Editor in there and use it under OS/2.  As with OS/2 PPC, you can have rexx.exe in there.  The 7.00 version does not like OS/2, but the 7.01 (2000) version is quite fine under OS/2.

For a DOS/OS2 history see is my website.  The two big files there (polygloss and metgloss), are maintained in a markup language that is written in REXX.

Games / Re: Hearts Card Game
« on: October 08, 2021, 02:55:00 pm »
I know how to play hearts as a game. 

There's a program called 'mshearts' that works under winos2.  It uses a few files, but can be freely downloaded from Win16 patch sites.  You can play against three computer players, or three over the network.

You play the game by playing 'tricks', that is, whoever has the 'lead', puts a card (of any suit), and other players follow with cards of the same suit.  If you have no card of that suit, then you can play any other card.  So if I lead something like five-diamonds, you have to put a diamond-card if you have one, but any other card if you don't.

The highest card of the same suit as the lead card wins that trick and becomes the lead.

The object of the game is to have the lowest score when someone gets 100 points.  A point comes from every heart card in tricks that you win (whatever the lead), or 13 points from the Q-spades.  If you get all of the points, then everyone elses' score goes up by 26, while yours stays as it is.

It's in my OS/2 themed "Windoze" .  There is a good fraction of Win-OS/2 in there as well :)

The lotus installer is a bit picky about what file system etc it installs from.

I installed SmartSuite and Amipro from a local directory (c:\setup\ss173 and c:\setup\amipro), and from a cdrom image I made with mkisofs under Vista 6.1, it did not complain about either.  The next test is to poke the suit.ri file into the directory before installing it. (This is the registration information data, made by install if not present).

Applications / Accelerated Installs
« on: October 08, 2021, 01:46:28 pm »
The current project is Accelerated Installs.

The idea is to reduce the time from a clean install of the OS to full working order.  While one can use something like Ghost or pre-installed zip files, I desired to have a fair bit of flexibility in this.  A lot of this is cross-platform, the ideas from one source copied to another.  Some of this stuff dates back to 1992.

The bulk of programs are either copied pre-installed, or pre-registered.  This means, for example, inserting the registry keys in before installing the program.  PMView, Larsen CMD, File Commander/2 work like that.  Strategically placing parts of the INI file work for GSView, Smartsuite 1.73.  4OS2, EFComm and OS2CMD already have their reg keys in the install.

Lotus Smartsuite 1,73

The slipstream was successful, so it installs on one run.  There is a version 1.60 + update on the eCS 1.0 disk.

Graham Utilities. 2.10

This involves a service pack, but the install can be streamlined somewhat.  The idea is to modify the eCS 1.0 install version to handle this without having to reboot.

TinyEdit and QEdit. 

These look for supplemental files in a hard-coded directory or the current directory.  Without the hard-code, T and T2 will try to open Thelp in the current directory.  Reconfigured to use c:\use\thelp.  Likewise Q dos and os2 look for spell-check in a hard-code directory.

Cmd2exe and Bat2com

These are variously OS/2 and DOS programs that produce a loader for programs, so that you don't have to modify config.sys or autoexec,bat and keep the program off-path.  Bat2com from Foley Hitec "Turbobat", which seems to work under HPFS.  (the pc-mag one doesn't). 

4OS2, Tcmdos2, Pmview, filejet, jetcmd, volkov commander, boxer, and lucide all work under this.  jetcmd and filejet can have their environment variables set in the loader.  boxer is DOS, OS/2, TKO and EZ versions.  FC/2 can be off-path, as long as you load it from an on-path file (eg fcw),

There is a Windows proggie of this name (Jim Lawless, 'com2exe'), but it allows includes of other files on top of just a batch compiler.

At the moment, I start 4OS2 through a CMD2EXE program.  This allows me to move it off the path.  It would be interesting to see what this things of that, except so far, I've only implemented that setup on eCS 2.2, nand not the Acra506  machine.

Both machines are on VPC under Vista 6.1 (Windows 7).  There's been a bit of Accelerated Installs done on both of these, since this is the current project.

Programming / Descriptions for OS/2 Book files (*.INF)
« on: October 08, 2021, 12:45:25 pm »
I wrote this little rexx script, to describe .INF files under 4OS2, 4DOS and 4NT.

It basically extracts the title from the INF file, strips the '00'x bits and tells the 4os2 session this is the file.  At the moment it handles only one file at a time, which means that you run "select infdesc (*.inf)" at the command prompt.

It can tickle some bugs in regina.rex (os2), in that if the description has no spaces, the program will read it as two files, and under 4NT, the files have quotes around them, which 4DESC does not like.  But generally it works quite well.

Code: [Select]
/* rexx */
parse arg infile
call stream infile, 'c', 'open read'
desc = charin(infile, 108, 48)
call stream infile, 'c', 'close'
desc = strip(desc,'B','00'x)
if desc = '' then do
  say infile' has no title'
else do
  'describe' infile '"'desc'"'

Most of the stuff in the second bit is simply intro, it isn't the first part of the code, just some random insert to it. 

It's actually an extproc command I run under 4nt.  The program that accepts this is weave.rex, which is also written in a similar style on a simple print on/off tangle.rex.  So tangle.rex is used to compile weave.rex, which is used to write all sorts of other things.

The bits of code that are 'commented out' or not included in the compile can still be in the source, but simply bypassed in the compile.

The program is handy enough that you can write a number of matching code pieces to different files, like write a matching 4DOS.INI and 4OS2.INI at once.

rxc.cmd is the command-line calculator, it's 22.170 bytes, the source code is 37.249 bytes.  The !topic is the 4dos help topic header, is what I use for bait for a folding editor.    This is what turns up on the fold.
