Quick question on a Perl Code!by dudydude (Novice)
|on Jul 13, 2011 at 21:36 UTC||Need Help??|
dudydude has asked for the
wisdom of the Perl Monks concerning the following question:
Hi fellow Monks, I am reading a code that somebody wrote and I am trying to make sense of it.
What does it mean if they pass a ($) or ($$) to a subroutine?
PLEASE NOTE I DIDN'T WRITE THE WHOLE CODE INSIDE, BUT IT IS A SUBROUTINE
WHAT DOES $ STAND FOR?
