This is a pretty simple question, and I've been getting along fine without
asking, but I'm starting to get curious, how does one allocate all the memory
possible to 1 pointer.  I've been using these 2 lines I found in someone else's
source (I don't think they should mind)...

size=MaxMem (&grow);
size-=65536;

now, do a NewPtr (size);

actually, it used to be:

size=MaxMem (&grow);
size-=32768; (for one code segment?)

but I doubled the number to accommodate 2 code segments, the one
currently active, and the main one, since I wasn't doing this from the main
one.

The "size-=32768" IS to not run over the main code segment, right?

anyways, it seemed somewhat silly to include the current code segment as
purgeable space, I can't think of any instance when you would want to allocate
over it.  So my question is, is there another way to allocate all the space
possible (not including any active code segments)?
