Introduction To TI-83+ Programming

By Alp Öztek

First of all we must be clear on the point that, you will NOT learn how to be a great programmer at the end of this article series and you can NOT write very complex programs since your TI 83+ has some limits. You will NOT be able to write games like Doom or Half-Life at best you can write a game of “pişti” if you are exceptionally talented and you can write some programs to help you in your classes.

The in-built programming language of the calculator is called TI-Basic and it is very similar to QBasic which is a programming language for computers. To access the TI-Basic editor to create a new program, all you need to do is to turn your TI on, press the PRGM button (which is the middle button on the third row) and you will see a menu that has three columns: EXEC, EDIT and NEW. The PRGM button is the button you shall press for anything related to programs.

In the EXEC column, the programs that are currently installed in your TI are seen -note that this column only shows the programs, not the applications. To execute or run a program you must use the up or down arrows until the cursor comes to the number next to the name of the program and then press ENTER. An asterisk near the name of the program indicates that the program is archived and cannot be run until it is unarchived. To unarchive a program, you must press 2nd button and then the + button, on top of which the letters MEM are written in yellow. This will display the memory menu. We want to unarchive a program so we choose the second choice, which is “Mem Mgmt/Del…” by pressing 2 and then the seventh choice “Prgm…” by pressing 7. This will display all programs in your TI and all you need to do is to press the up or down arrows until the cursor is next to the program you want to unarchive and then press ENTER. The same process can be repeated to archive a program.

Back to the PRGM menu, the second column, which you can reach by pressing the right arrow once, is the EDIT menu. This menu displays all programs in the memory of your TI that are written in TI-Basic and not marked hidden. By choosing the program you want to edit and pressing ENTER, you can see the source code of that program and edit it.

The final menu, which is the NEW menu, has only one choice which is “Create New”. Choosing this, you will be asked to give a name to your program. The name can have ...
