In brief, I was very disappointed with this book. From the cover, I thought it would have been full of dodges and programming goodies which would make life easy to show off nice features of the machines: instead it consists of 101 short programs in Basic each demonstrating a simple task like calculating averages, rolling dice or currency conversion.
The level of programming is very simple; arrays, for instance, are never featured, and hardly any attempt is made to show off special features of the computer like user-defined characters. But what really annoyed me was the number of programs which had POKEs to the sound generators... but which were for the Vic. There were sixteen of them, and no mention was made of the fact that they'd run only on the Vic. Any C64 owner would get very frustrated at these not working, and there is a chance that the C64 would crash in some cases.
If you've just acquired a Vic and are learning Basic, this book might be of some benefit: I could not honestly recommend it to any C64 owners. Overall, disappointing - ok maybe for Vic owners.
