Greetings!
In the "subroutines" thread, the original poster declared his
FoulParser subroutine with this line:
> > sub FoulParser($);
Then, Steve Grazzini suggested that subroutines might look like:
> sub foo ($$) {
> my ($first, $second) = @_;
> }
What do the dollar signs mean? I've never seen them used this way
before!
Thanks!
RobR
