Bad example: somehow I never find that I already know isascii(c) before calling isdigit(c), so for ``portability'' I always have to use both. So it wouldn't be rare usage. On the other hand, I also see absolutely no use for a three-valued isdigit above a simple isascii && isdigit; I suspect most other programmers agree. ---Dan
