|How to Design Programs|
|September 26, 2003|
In June 2010, PLT Scheme was renamed to “Racket”, and DrScheme became “DrRacket”.
For use with the How to Design Programs (HtDP) book, we encourage you to download and use DrRacket. It includes all the teaching languages that HtDP and HtDP/2e rely on.
For those of you who wish to download old versions of the software, please go to the old DrScheme pages.
