Appendix E: Calculator Programming Examples
Although you can create and edit your programs using the calculator keypad, calculator programs are most
easily dealt with on a computer using the TI-GRAPH LINK software (available from
www.ti.com/calc ). Once
written, the program can be transferred to the calculator via a TI-GRAPH LINK cable (available from Vernier
Software). Samples of various types of programs follow. Each of the following programming examples
includes both program commands and comments explaining what the commands do. These examples are
written using a TI-83 calculator.
