Does  anyone know what happened to the Alsys OS/2 Ada compiler (& toolset)
after Alsys folded?  I know the Win NT & Unix versions got picked up by
Aonix but I have never seen any mention of the OS/2 version on their
website.  I wrote several Ada programs for OS/2 that are still in use but
the current version of OS/2 (V4.5 convenience pack) crashes when running any
of these programs.  I dug out a copy of the compiler and it will not run at
all - not the install program, the compiler or any of my old ada
executables - not even the "Hello world" one liner.  Obviously there is a
major mismatch somewhere - perhaps in the system dlls.

Ok - I know OS/2 is dead but some are still running it and my client is one.

Our copies of the compiler are V5.5 circa 1995.  I had heard there was a
later version 5.6 maybe.

Is anyone still using this compiler?  Was there a later version?  TIA

Paul

   I had never heard of an OS/2 version of the Alsys Ada compiler before, so I
cannot help you in that line of investigation. In general, older OS/2 programs
run very well on later incarnations of the operating system. The Convenience
packs (v. 4.5) incorporate major changes to the kernel, but I would hesitate to
blame that without further evidence.

   Ada on OS/2 is not dead, though. Gnat on Intel PC started out as an OS/2
program, before Windows NT became the major PC operating system. Although ACT no
longer provides ready-made binaries for the OS/2 version of the compiler, newer
versions (up to the current 3.15p) are available thanks to the efforts of Dave
Parsons.

   I use gnat 3.14p on OS/2 (v. 4.0) very regularly on fairly large programs and
have never had a problem with it. I have so far not moved up to 3.15p (sorry,
Dave), but I hope to do that one of these days.

   Gnat is of course Ada 95, whereas Alsys was Ada 83. That in itself should
present no great problems. There are just a few minor issues which can be easily
fixed. But if any Alsys-specific libraries are involved, that would of course be
a different matter.

   Feel free to contact me privately, if I can be of any further assistance.
