Terrible book for learning Perl. As an example, I needed to know how to add an element to the end of an array. So I went to the 'Variables and Data' chapter where there is a section on arrays. Well, it mentions how to create an array, how to change the value of a specific array position and thats about it. I had to search online to find out how to do a very basic thing--add to the end of an array. The 'Variables and Data' section makes no mention of using 'push(@array, "whatever")'. I keep having to search online for very basic things that should be easily found in this book. Oh, and starting the book by talking in-depth about 'Perl parsing rules'--I got confused from the start. Definitely not something you want to learn Perl with.
