Sorry... serves me right for modifying my example after having compiled it. UCHAR_MIN doesn't exist because the only permissible minimum value for any unsigned type is zero. My original program iterated over [CHAR_MIN,UCHAR_MAX], but I realized that that was incorrect and changed it in my message without re-testing. In any event, that particular error does not change the fact that Standard C requires the ctype(3) routines work for all possible values of an unsigned char, and EOF, and the old isascii() kluge should not be carried over into new code. (If you are concerned about portability to old, broken systems, include a working ctype(3)...) -GAWollman -- Garrett A.
