Query: Impossible to use. Don't waste your money.

This book is by far the most confusing, rambling, badly-written, and unedited programming manual I have ever seen. The information is just thrown together haphazardly and without logic. The author jumps randomly between subjects and there are no readable threads. Finding anything in this book is impossible. I took forty minutes trying to find out how to declare a variable, and finally threw the book in the trash. Don't waste money on it, period!
