First of all: I know that you are a newbie here at the Monastery, (your XP shows all too well...) and being a newbie, you need to learn some of what we do here, and how things work around here. One of these things you need to learn, is how to correctly title questions. Your question is legitimate, but your title is not very specific in its description. char. VS char. doesn't really give us an idea right off hand what you are asking. (Do char's fight eachother or something?)

Second: Have you even read any Perl-related learning books for beginners? It doesn't seem like it. Check out Learning Perl sometime, it will help you get up and on your feet quickly.

Otherwise, keep at it, and welcome to the monastery.
