Questions tagged [ti-basic]

TI-BASIC is the official name of a BASIC-like language built into Texas Instruments (TI)'s graphing calculators, including the TI-83 series, TI-84 Plus series, TI-89 series, TI-92 series, TI-73, and TI-Nspire. The capability to write programs in TI-BASIC is automatically built-in to Texas Instruments calculators.

Forms of TI-Basic

TI-Basic comes in three distinct forms, TI-83, 68K, and TI-NSpire. While these forms have much in common, they also have noticeable differences that make code written for one from almost completely incompatible with the others. For this reason it is important to explicitly state the form of TI-Basic you are using in any questions.

  • TI-83 Basic
    This is the most common form of TI-Basic. It refers the form of TI-Basic found on both TI-83 and TI-84 series of calculators. Even within this form of TI-Basic, there are variations in the availability of functions between calculators.
  • 68K
    This form of TI-Basic is far less common than TI-83 Basic. 68K TI-Basic is found on the TI-89, TI-92 and Voyage 200 calculators.
  • TI-Nspire
    Generally the least common form, this is only found on TI-Nspire series calculators. Due to the far superior processing power TI-Nspire calculators have, this form could have more potential than the others, but limitation in regards to input and output renders this form largely unused.

Is there a way to store a list when programming a TI-83+?

Out of curiosity, I'm beginning to learn how to program my TI-83+ calculator. Part of my latest program involves storing numbers in a list. How can I add items to a list on a TI-83+ and how can I loop over them/access them?

isolate for variable in equation with the ti 84+ ti basic

I am making a system of equations solver. it works great, but I can't input any equation. It needs to already have the right side be y= so I can't do: 2x + 5y = 19 x -2y = -4 I have to simplify to: y = (19 - 2x)/5 y = (-4 - x)/-2 Is there any way…

TI-BASIC: Why are there question marks in a menu?

I'm writing a program in TI-BASIC, for use on the TI-84+CSE, which begins with a Menu( operator for simplicity when it comes to choosing a branch. The menu, when the program is executed, displays question marks (?) for the final two elements which I…

Check if a list is defined and avoid the "UNDEFINED" error

In the original TI-BASIC (for TI-83/84+) is there a way to check if a list has been defined? Currently calling dim(⌊LIST) will return an error if the list is not defined. Is there a way to handle that error gracefully? Possible Workaround: The only…
