In this case you are not declaring your variables, adding a 'my' before them will fix the issue in most cases. perldoc -f my perldoc strict http://perl.plover.com/FAQs/Namespaces.html For more, especially that last. If you start out in the habit of including 'my' before your variables, then when you screw up the name of one of them, then strict will yell at you. This is only one very small example of how it can help you and save you time, no more hunting for misspelled variables. http://danconia.org -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
