VOLITION

[Chris Chiesa]

I just happen to have a manual for Volition Systems Modula-2 right here
on my shelf.

Author: Richard Gleaves

Much of which was later published by Springer Verlag as "Modula-2 for Pascal
Programmers." Gleaves's style was as simple, direct, and elegant as the
language.

And here I am, thirty years later, trying to boot, under vDos, copy of Volition Systems Modula-2 from a college course I took in 1985. The main screen comes up, but it never gets to accepting top-level-command input; just sits there chewing about 48% of the CPU. I suspect it may be looking for a second floppy, or a second Modula-2 volume (I'm booting something named SYSVOL, from the same "floppy" as M2.exe itseIf). Clearly, *something* it needs is not available where sought.

Randy, if you still have that manual, and ever see this message, does it say anything about system prerequisites that I need to meet?

The Internet Archive has a 405-page manual on Volition Systems 0.3j
(https://archive.org/details/bitsavers_volitionSy20.3jIBMPC_14753891),
which may or may not help.

A naive hint would be to try to run a TSR that logs what files are being opened.

You might be better off downloading a modern copy of XDS and adjusting
your source code to compile with it. It was surprisingly good.

I don't recall Volition being a player back in the 80's.
JPI/Topspeed M2 & Logitech were the main ones.

Is the Logitech compiler still out there?

A 1987 post in comp.lang.modula2 by Randy Bush titled 'One-pass' Compilation Issues mentions the Volition compilers. Here is an extract

--------------------------------
Volition's p-code system (they also did a completely different MC68000
native system) was derived from the one-pass P2 compiler, and therefore
could not implement the language as specified in PIM-2.3. They added
FORWARD to procedure declaration, disallowed use before declaration, and
did not support mutually importing internal modules.

There was no negative user feedback on these restrictions. As the p-code
compiler was quite fast for an interpretive implementation (2,000 lpm on
a floppy based 68000 at 8MHz), the users seemed to feel the trade was worth
it. This was in '81.

Volition's native code compiler for the 68000 was written with the same
restrictions. This product has been acquired and developed further by
Masthaven, and their impressions of user feedback would be useful in
evaluating the impact of one-pass restrictions."
--------------------------------

I have also used Volition's Modula-2 on a Sage 68000 computer in the guise of ScenicSoft Modula-2 and Pecan Modula2.

A summary of the evolution of Logitech Modula-2 is here:

I suspect that v4 of Logitech Modula-2 was a rebadged version of Stony Brook Modula-2. The Stony Brook compiler is now available as freeware as ADW Modula-2
