For certain values of "must". I'm fairly sure that the Ada standard does not require support for 64-bit integers, and I've worked with Ada implementations that didn't support anything bigger than 32 bits (System.Max_Int = 2**31-1). If you want to argue that such an implementation is broken (even though it's conforming), I won't disagree. -- Keith Thompson (The_Other_Keith) kst@cts.com San Diego Supercomputer Center <*> Schroedinger does Shakespeare: "To be *and* not to be"
