However, I think that a hash could be used, but that you are using the wrong value for the key. If you are given the string '10.00.00.00.aa.56.9b.7a' and want to know that it is associated with the value '22:5a', then '10.00.00.00.aa.56.9b.7a' should be the key of the hash, and '22:5a' should be the value. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
