Please note:

There are plenty of errors in this book. There are typos, logic errors, program errors, programs that don't quite follow the text, etc. Some have been pointed out, some have been fixed in the SAVEd or LiSTed BASIC files, others have just been left as is. If you see an error in this web version of the book, it is most likely a "loving recreation" of the original.

Any errors that have been corrected or are just being pointed out will appear in a box like this or text with the same background color.
