The Code

All the code in the book, as a zip archive (211 Kb).

This is the original code. It was tested under PLT Scheme versions 372 and 4.2. It shouldrun unchanged in Racket 5.1.3.

Don't try to run this code under any more recent version of Racket. Instead, use the version at Github and use Racket 5.3.6.

If you are feeling adventurous, you can try to adapt the code base to use the rackunit testing framework instead of the kludgy one I threw together for the book.
