Well I finally installed System 7.0 on my Mac IIcx and applied the
THINK C patches for THINK 4.0.5.  So far no problem.  Excpet reading
the documentation for the updater I see that THINK is only 90%
compatible with System 7.0 and the 10% that isn't compatible is....
AARRRGGGG...  virtual memory!  THINK C generates 32-bit clean apps but
THINK C and its debugger apparently cannot run with virtual memory
turned on (what they mean by "cannot run" or "doesn't work with" is
kindof vague really).

This isn't good!  A project I'm working on REQUIRES that virtual
memory be turned on while the app is running.  Now how am I expected
to debug a program which wants to see a full 13 megabyte address
space?  I can't so I'm hosed.  Does ANYBODY have any workarounds?  Is
Symantic going to make THINK C compatible with VM and when can we
expect an upgrade?

Right now I'm thinking of switching over to MPW C.  I have deadlines
and I can't afford to just sit around waiting for Symantic to think
about it.

MPW works when virtual memory is turned on doesn't it?  Would a port
from THINK C to MPW C be difficult as in, can I just compile THINK C
.c files without modification and expect it all to work under MPW?  I
know MPW isn't the elegant sportster that THINK C is, but presumably
it works and that's what I need.

Thank you all in advance for your replies....
