	This is partially true. You're allowed a maximum of 32K of executable
code per code segment, but that is *not* a 32K limit on total program size.
You can have as many segments as you needs, and every single
development system I've come across (TML Pascal, MPW, LSP, LSC) has
provision for you to create multiple segments. Usually, the linker will
tell you if a code segment is too big, and allow you to create
new ones (Lightspeed C and Lightspeed Pascal make it especially easy).

	As far as this limitation being a "problem" with the Mac OS, I
doubt it. It *is* a limit, but the 32K segment limit assists in
using memory efficiently -- unused code can be dynamically unloaded and
reloaded, with very little programmer intervention. (You have to call 
a routine to unload a segment, but loading is done automatically.)

If you really wanted to, you could write your own segment loaded, and
then have segments as big as you want.
