Glad I could help. A couple comments though, you probably want to initilize @schedule with an empty list.
@schedule = ();

The other is you usually don't want to assign to @_, depending on the context it might cause subtle bugs. @_ has some magic associated with it. For instance, in a sub, @_ acts as aliases to the passed arguments. (Example below)

It appears assigning to @_ makes it lose it's magic so I don't think it is a problem here but it's probably a dubious habit to form.

#!/usr/bin/perl -w use strict; my ($foo,$bar,$baz) = (1,2,3); print "$foo, $bar, $baz \n"; # Prints 1, 2, 3 foo($foo,$bar,$baz); print "$foo, $bar, $baz \n"; # Prints 5, 10 , 15 sub foo { foreach (@_) { $_ *= 5; } }
