MPW DOES NOT have the 2 byte integer problem! MPW (more accurately,
the MPW C compiler) integers are 4 bytes (Thank god!).

Arrays larger than 32K are also no longer a limit. New compiler options
allow for arrays that are very long, but the code is slightly less
efficient for these arrays ( OFFSET.W(Areg) versus OFFSET.L(Areg) ).

Don't know about that #defined positive number thingy unless it was
related to the 2 byte integer problem.
