true but if you have warning enable (which i think is a good idea), Perl will warn you about this even the string starts with a number but doesn't contain purely number. so if you want to avoid those warning, you can disable warning (which is not recommanded) or you have to enter a pure number. :-) david -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
