I have a Mac II with 2 MB RAM.  I have written and run a program
that needed a half megabyte array.  I used LSC 3.0 & mlalloc().
It worked fine.  I had a little trouble with the declaration
of mlalloc() originally - it had something to do with (void).
I don't have LSC 4.0 (yet?), but doubt that this would be broken.
I recall not being able to debug the program with the array at
its largest, but the debugger was extremely useful with a reduced
array.  RAM is cheaper again, and i'm looking at expanding my
Mac to 5 MB.  BTW, the program had a runtime of about a half hour.
Not your typical Mac program.
Stephen.
