Query: This is more of a giant program listing than a book

If you are some kind of gear-head that loves to read through program listings, this is the book for you, bubba! It is about 90% code and 10% commentary on the code. Dorfman even chooses classes that only a true gearhead could love, like 'key', 'mouse', 'event', 'window' etc. rather than abstracting real business-world items such as 'customer', 'account', 'order', etc. As if that's not exciting enough, the platform of choice for this text is DOS (yawn).
