Since the TI-99/4A cannot realistically support an on-line help system, this site has been created to document all the features of TurboForth. Quite literally an online-help system! All the Forth words available in TurboForth from power-up are documented here with examples, stack signatures etc. There is also a section on what the Forth language "is" for new-comers to the language. Technical information, such as the memory map are also available, in addition to numerous support libraries. Source code is available to browse online, in addition to a downloadable archive.

You are enouraged to browse this site. You can communicate with the author, and other like-minded TurboForth users via the mailing list. If you want to communicate with other Forth-minded individuals (there's more of us than you think!) then comp.lang.forth is a good place.
