You will probably never need to do this or even worry about it. Especially if you are new to Perl.

Heh, just an interesting side note. One of my first Perl projects was to modify prewritten scripts used for Radius time accounting. The data munging was all based on $\ = '', $PREMATCH and $POSTMATCH. Not a pleasant introduction to Perl. Fortunately, I had a camel. Unfortunately, the monastery didn't exist yet.
