Perl Programming at Wikibooks

Perl is a programming language invented by Larry Wall to process text. The programming language has been changed many times to do some other things. Some of these things are tasks like making web pages show information in a better way than before, or take information and show it in a way that makes more sense to people. Perl code is written using some symbols besides letters and numbers.
