As Shawn said, the join doesn't append a newline after the last element. Rob
No, it doesn't, but there is an extra "\n" being tacked on after the join. This is sloppy and confusing, which is why the map version is better. the join function is not the right function to use here. If the join character was ",", then join would be appropriate. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
