TI-BASIC

It has been suggested that this article be split into articles titled TI-BASIC 83 (Z80), TI-BASIC 89 (68k) and TI-BASIC Nspire (ARM). (discuss) (February 2019)

TI-BASIC is the official^[1] name of a BASIC-like language built into Texas Instruments' graphing calculators. TI-BASIC is a language family of three different and incompatible versions, released on different products:

• TI-BASIC 83 (on Z80 processor) for TI-83 series, TI-84 Plus series
• TI-BASIC 89 (on 68k processor) for TI-89 series, TI-92 series, Voyage 200
• TI-BASIC Nspire (on ARM processor) for TI-Nspire and TI-Nspire CAS

TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation.^[2][3]

For many applications, it is the most convenient way to program any TI calculator, since the capability to write programs in TI-BASIC is built-in. Assembly language (often referred to as "asm") can also be used, and C compilers exist for translation into assembly: TIGCC for Motorola 68000 (68k) based calculators, and SDCC for Zilog Z80 based calculators. However, both of them are cross-compilers, not allowing on-calculator programming. TI-BASIC is considerably slower than the assembly language (because it has to be interpreted), making it better suited to writing programs to quickly solve math problems or perform repetitive tasks, rather than programming games or graphics-intensive applications. Some math instruction books even provide programs in TI-BASIC (usually for the widespread variant used by the TI-82/83/84 series).

Although it is somewhat minimalist compared to programming languages used on computers, TI-BASIC is nonetheless an important factor in the programming community. Because TI graphing calculators are required for advanced mathematics classes in many high schools and universities, TI-BASIC often provides the first glimpse many students have into the world of programming.

Wikibooks has textbooks on TI-BASIC programming:
