  One other thing is that Str255s are different: in LSC, they're arrays of characters,
in MPW, they're a struct, which means you occasionally have to do different things to
them.  The most annoying, however, is the fact that in MPW, when you try to call a
Mac function that takes a string, it assumes you're transferring a C string and
messes with it. It also insists that you pass variable of type Point by reference,
rather than by value. Fortunately, it provides all-caps versions of the functions
that work just like LSC's, but it's a pain in the neck anyway (all this may have
been fixed in MPW 3.0, in which case just ignore me.)  Anyway, I've just got a
header file that includes lines like:

#define DrawString DRAWSTRING

Its a kludge, but it works.
