TI-89.org Programs
Here's a list of some programs written in TI-89 BASIC. If you don't have a graph link, it is possible to download the TI-89 Graph Link software, open the source code, and copy them in manually (although this can get a bit boring to type). If you wish to write programs yourself, you can read the Programming chapter in the TI-89 manual, which can be found online in PDF format here. The reference sections in the back are also useful if you wish to program, since they contain information on the syntax of several TI-89 functions. If you want to write programs in C, TI-GCC is the compiler that most people use.

Super Cool Text, Version 1.0 |  |
Super Cool Text is a program that allows you to animate text in several ways. It includes a Super Slope mode, which creates a really neat scrolling animation of the typed text, a Random mode, which randomly and repeatedly displays the text around the screen, a Bouncing mode, which bounces the text around the screen, and a Trailmaker mode, which bounces the text around the screen and leaves diagonal lines where it goes. Try it!

Super Riemann Sums, Version 2.01: |  |
Super Riemann Sums is a program that calculates Riemann sums for you. It can find the left Riemann sum, the midpoint Riemann sum, the right Riemann sum, the Riemann sum with the Trapezoidal rule, and the Riemann sum with Simpson's rule. It is made easy to use but is also very efficient. Try it!

GetKey, Version 1.00: |  |
GetKey is a simple programming utility that allows you to find the numerical key value for any key. This allows you to get input from keys inside of programs (as opposed to text dialogs). An example of its usage is included in the readme for novice programmers. Try it!
