"So the concept is new to me, so can you please explain..."

OK, yet another answer with no code :-(

When i had my first impact with Perl some years ago, i got stuck, what else.

So i bought a book and started reading. This was the way i did it.

I'm not a friend of this "self-taught, reverse-engineering is good bla, bla" approach. One needs sometimes a good advice.

But before this, there must be a personal effort... AKA RTFM

This is my recommendation - to you.

Update:

Oops, i published too fast...sorry.
