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. |
This page contains the character codes used internally by the calculator. This table can be useful in particular with the char() and ord() commands.
Characters in the following ranges can be used for variable names:
- 48…57 (numbers, as long as they don't begin a variable name)
- 65…90, 97…122 (the usual alphabet, case insensitive)
- 128…139, 141…148, 181 (Greek letters, case sensitive: ω is not the same as Ω)
- 192…214, 216…246, 248…255 (international characters, case insensitive)
Note that value 2 (STX) cannot be used on the home screen, because for some reason it does not exist in large font.
