At this point I'm going to gently but firmly recommend that you stop and read
some documentation on references, specifically:
* 'perldoc perlreftut' (<http://perldoc.perl.org/perlreftut.html>)
* 'perldoc perldsc' (<http://perldoc.perl.org/perldsc.html>)
You can read them on the web with the links, or in the shell by running the
command on the left.
The "wrap the ref in brackets and the sigil for the underlying variable type"
trick is a pretty fundamental concept when you're using references; I think
you'll have a lot more success and a lot less frustration if you read those
docs now, particularly since you seem to be going down a "try to intuit how to
make things do what I mean" route.
chrs,
john.
