Why "*unsigned* char" I know that "char *", "unsigned char *", and "signed
char *"
are pairwise incompatible, per ANSI, and IBM's C is the only processor I know
that
enforces this. I once needed to correct a shareware author on a transgression.
(IIRC, he used a cast as an L-value.) But I'd expect a z-centric product to
rely on
the native unqualified construct. Greater portability?

That appears to be Charles agreeing with Shmuel's uncharacteristically
agreeing with Charles's agreeing with me.
+1. Me, too.
