I know you're just doing your schtick and it’s nice to present a literal answer. Can’t -- that. Still, many, if not most beginner/self-taught hackers arrive at the symbolic references approach on their own. I did and it cost me plenty; slowed me down tremendously for the first year I was slinging Perl and made my code a hateful mess 5 times the size it should have been.

So, I attach that for the OP. This works. The other suggested approaches are a better way to get your head in the game.
