Chipmunk Basic

Chipmunk Basic is a freeware interpreter for the BASIC programming language maintained by Ron Nicholson. Chipmunk basic was originally developed for the Macintosh and publicly released in 1992. It has been ported to Linux and Windows. The "windowed" Mac version includes agraphics drawing commands. It also has object-oriented capabilities.
The current version of Chipmunk Basic is based on a public domain, Pascal implementation by David Gillespie.
In January 2015, a Cocoa version was released that may lack features from the older Carbon-based OS X port. The most recent release is Version 1.368.2210, published Nov 11, 2022.
