Sorry. The predominant view has proven once again to be justified. I'm sorry I let my optimism lead me to purchase this book to find out. It really is a badly edited collection of unexplained and useless gimmicks. If there is a concept presented that has any worth in learning to write your own code, than it is extremely well hidden among the error laden examples.
I have every book on RealBasic available now, and the O'Reilly book is the only one that truly helps one learn the product AND programming. On the other hand, Eric's book is good to build confidence without much lasting programming value. This book cannot claim to teach or build confidence - although I found it an interesting exercise debugging and proofreading the text and code - representing perhaps the only real experience to be gained through the use of this text.
