You are running the subroutines. These are all equivalent (note that the third example only works if the sub has been declared earlier): &get_number; &get_number(); get_number; get_number(); You have to use the 'sub' keyword to declare subroutines. sub get_number; perldoc -f sub However you usually only have to pre-declare subs if you are using prototypes. Please read the perlsub.pod document to find out all about Perl's subroutines. perldoc perlsub John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
