There are lots of functions in the standard which are predicates in that they return generalized booleans but on the other hand return something "useful" if the result is not NIL, e.g. MEMBER or STRING<. And some of them might also end in -p (digit-char-p) -nick _______________________________________________ pro mailing list [email protected] http://common-lisp.net/cgi-bin/mailman/listinfo/pro
