It looks like you just began your journey into the wonders of perl. May I wish you much joy and enlightment on your path?

Read about references in perlreftut and perlref. Use that search box in the upper left corner and Super Search at will.

Just to make a reference: 

$foo = 1;    
$fooref = \$foo;      #a reference to $foo
$foovalue = $$fooref; #de-reference $fooref

[download]
That's how it works with scalars. With arrays: 
@bar=0..10;
$barref = \@bar;
@barvalue = @$barref;

[download]
You see? Use the backslash for making the reference, and precede the reference-scalar with a $,@ or % (hash) to get the values.

Hope this helps,

Update: Unfortunately, perlreftut cannot be found on this site, it is probably only found in the 5.6 distro. Thx 2 stephen for pointing that out. New link to the pages of Dominus.
