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 command turns on all or a group of functions.
FnOn [optional function numbers]
Menu Location
- Press F4 from the Homescreen to enter the OTHER menu.
- Press 7 to select the FnOn command.
This command works on all calculators.
The FnOn command turns on one or a group of functions. The optional argument specifies which functions are to be turned on, and if there is no argument, then all the functions are turned on, not just the specified functions. This is used mostly to turn back on functions after they are turned off by the similar FnOff command, or it is used to turn back on functions after a program that has used the graphscreen.
:FnOff
:FnOn 4,7,9,20The above code will turn off all functions, and then it will turn on only functions 4, 7, 9, and 20. This is useful if you want to graph only a few functions, but still have the rest of the functions stored in the calculator.
Error Conditions
260 - Domain error happens when the optional function argument is not in the range 1-99.
