Sample Programs

We're glad you came by, but you might find what you're looking for elsewhere.

TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it.

Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

The programs linked from this page are complete (if simple) programs, presented with source code and an explanation. They are meant as a way of putting everything that is on this guide together into an example of what TI-Basic programmers like you can do. For readers who learn better by example than by explanation, these games are also a great way to learn the techniques explained in this guide.

These programs have been fully optimized, except where this would interfere with readability. For example, the names of variables could easily be converted to single characters — this was deliberately left undone. The individual pages explain what would be done to finish the job of optimization.


Tunnel Racer — a game of reaction in which you race through a twisting tunnel, trying to avoid crashing.

RSA Encryption — an implementation of a popular public-key encryption algorithm.

Symbolic Division — a function that does symbolic division.
