I finally bit the bullet and installed MSC 6.1 on the production machine at
work.  The environment is an 80386 ALR running at 20MHZ, 6 megabytes of
memory, XENIX 2.3.3, VPIX UPDATE A, 2 serials, parallel etc.

After everything loaded I cooked up the basic hello world program and
compiled it with: cl /Zi /Od hello.c

The executable was generated but when I executed it VPIX crashed with
the following message: unable to execute two-byte instruction.

Odd I thought to myself considering that optimization is turned off.  I
recompiled the program with: cl /Zi hello.c

This time VPIX dumped with a segmentation violation error.  I recompiled
the program with: cl hello.c and this time everything worked fine.

I kicked up the PWB and set the environment to compile with debugging
information (/Zi) and no optimization (/Od).  I told the PWB to compile
and execute and after grindig away for a couple of minutes the whole works
locked up tight.  I had to switch to another multi-screen and kill the
VPIX process to regain control.

Anybody have similar experiences running MSC 6.0 in a virtual environment?
I have two sets of installation disks (1.2 megabyte, 360 kbyte floppies)
and installation from either set causes identical behavior.  I like to
think of myself as a reasonable programmer but I don't think I would care
to function for very long without debugging information....

Any information, tests etc would be appreciated.  Please respond to my
address listed in the sig.  Thanks in advance for any information which may
be forthcoming.
