What am I overlooking? you are making a classic newbie mistake. tr (the prefered name for the y/// op) is NOT a regex and does not use regex syntax. it doesn't need [] as it always is character oriented. so rtfm on it some more and you will see how to negate its list of chars and that using [] is not only not needed but can lead to buggy code (the [] are treated as any other char and translated too). uri -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
