Query: Great Introduction to Perl

I did not have any previous programming experience before reading this book, just a bit of dealing with Unix. After reading it I was able to create useful programs which I had been wishing for. Some topics seem a little out of place, I do not understand why the chapter on subroutines is so early. Learning is a bit rough with no programming experience, but worth the work. I think of this as the language introdution by which all others are measured.
