What is a (Carbon) Boolean and how do I convert it to a Cocoa BOOL
(regardless of architecture)? Thx - m.

A Boolean is an unsigned char and a BOOL is a signed char. Since both define false as 0 and true as !0, you can simply cast one to the other. The ISA doesn't make any difference because it's a single byte.
