Yes, that's what I'm hinting at :~) A hash would be called for if you need to do repeated tests to see whether an element exists in the set. The downside to pulling the unique values with keys() is that you lose the original order, if that matters. Tie::Array::Unique will take care of the problem and preserve the order, while letting you push entries onto the array without worrying about creating duplicates. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
