That presupposes a knowledge off ASM functions though, which I don't have.

True, but that was a pretty unique bunch of Exception 13s.  I've never seen
all 00s before, and suspect such a major crash, that the bad instruction
had been cleared from memory prior to QEMM's report.  Just a guess, of
course.

I think I did once - 702TO704.ZIP comes to mind here.

rc> Upgrading to 7.5 requires a new evaluation copy.

No problem, as I no longer run native DOS, I no longer need to evaluate any
memory managers.  I almost bought QEMM once, purely out of guilt, but
decided that paying more for a 3rd party memory manager than the entire
operating system costs, was more than just a bit stupid.  Glad I didn't
now.
