There is a compiler option in MPW C 3.0 to permit >32K data (I haven't looked
at the pascal 3.0 manual yet).  Segments can be >32K (and could in 2.0), but
there remains the constraint that all externally-referenced entry points
in the segment have to be in the first 32K (segment-loader offsets).

I had the pleasant experience tonight of actually doing a compile in
BACKGROUND under MultiFinder, using MPW 3.0.  This was using (*ahem*) the
Aztec 3.6 tools, unchanged (and they laughed when I added spinning cursor
support!) to compile, assemble etc. under control of a shell script (output
of MPW make).  Being able to say (in effect) "make &" pretty well doubles
my productivity at the Mac.

I just took MPW 3.0 out of the box, and (despite intensive use of MPW 2.x for
almost two years) it looks like it'll take a couple of weeks to a couple of
months to come up to speed.  The boys in Cupertino have been very busy,
and they have added a LOT of VERY NICE stuff to the MPW environment.  Enough
nonsense about how expensive MPW is: this product is a class act.

The only disappointment is that I'll need a massive memory transfusion before
I'll be able to use the symbolic debugger; pity, if it is up to the
standards of the rest of the package it'll be nice to have (eventually).
Oh well, I've gotten this far with TMON...
