Please *do* remember the message. lc(chomp($input = <STDIN>)) is broken only because chomp returns the number of characters chomp'ed, not the chomped string... easy mistake. The argument is chomp'ed *in place* for performance reasons (at least it better be, because there's no other good reason for such an annoying mis-feature) chomp($input=<STDIN>) print lc($input) should work, but remember, 'lc()' returns a lowercase copy of its argument, and does not modify its argument!! chomp and lc are opposites in this respect. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
