Who are you?

How do I send programs to my calculator?
See documentation here.

Cool. Can I distribute your programs?
Absolutely! Source code is always included, and all code (including the scripts, CSS, and html on these pages) is licensed under the GPLv3 (or any later version).

Can I reuse your html?
Well... yes, but no. The license lets you, and sure, go ahead... but you probably want to write your own since this site is a prime example of table abuse...

Hey! Your program crashed my calculator!
Well, sorry. There's always a chance that something goes wrong. And, its not just assembly. (Assembly is the language most programs here are written in.) TI-BASIC programs can cause crashes too. If you don't believe me, try running:
:"
:expr(ans
It will crash.
