You could have kept the hash as a reference why do you say she wants to shift @_? that is the lesser style of getting an arg from @_. the better way IMNSHO is assigning to a list. shift is slower, doesn't work well for multiple args (one shift per statement) and it modifies @_ unnecessarily. there are times when it is useful but the primary method should be a list assignment. uri -- Uri Guttman ------ u...@stemsystems.com -------- http://www.sysarch.com -- ----- Perl Code Review , Architecture, Development, Training, Support ------ --------- Gourmet Hot Cocoa Mix ---- http://bestfriendscocoa.com --------- -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
