I remember from my C++ class that when you pass arguments to subroutines you can pass them either as a pointer to the real variable (so you modify the original if you change it), or as a copy (which you can change all you want and not affect the original).
Is there a perl equivalent of both of those two concepts? - B -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
