TI-Basic Z80 Programming
This book covers the Z80 processor's version of TI-BASIC.
TI-BASIC is a simple programming language used on Texas Instruments (TI) graphing calculators. The language is quite simple, and integrates many normal graphing calculator commands (such as storing variables or graphing) into its code.
TI-BASIC is very easy to program, especially when compared to assembly, which is the other main language that can be used to program TI graphing calculators. Also, programs written in TI-BASIC can have small file sizes, since common functions can be programmed with just one character (1-2 bytes), such as
Menu(. However, this makes execution of TI-BASIC programs very slow, since each line of code must be read and parsed before execution. Despite the crawling speed of TI-BASIC, it's appropriate for many simple programs.
Versions of TI-BASIC
There are two main versions of TI-BASIC in use today:
- The TI-BASIC that comes with the TI-89, TI 89 Titanium, TI-92, TI-92 Plus and Voyage 200 calculators. This is the more powerful version of TI-BASIC.
- The TI-BASIC that comes with the TI-83, TI-83+, TI-83+ Silver Edition, TI-84+ and TI-84+ Silver Edition calculators. This is a less powerful version of TI-BASIC, but is still fairly versatile. This Wikibook covers this version.
Please note that within these two versions of TI-BASIC, there are slight variations.
