TI Calculator Programs

TI 83/83+/84+

The following programs were written by Michael Lloyd of Henderson State University. They can be downloaded directly from his website, or they can be downloaded here.

The programs have extensions of .zip and are compressed. The files with extensions of .txt are text files of the programs containing more information. You will need to download and unzip the programs to transfer them to your calculator. Download a free version of WinZip to extract the compressed files.
You need a Graph Link Cable and the Graph Link Software to link the files ending with "p" or "g" directly to your calculator without opening them.
There is a special instruction for the cdistr program: If you open cdistr with the Graph Link software, the expression prgmFVAL will be interpreted incorrectly. If you get a syntax error, edit the program by replacing FV with alpha F and alpha V.
The programs zzinewt, zzmenu, zzrank, and zzrpdf are subroutines for other programs, so be sure to include them.
