TI-BASIC

TI-BASIC is the official name of several BASIC-like programming languages built into the graphing calculators made by Texas Instruments. It is a family of three partly incompatible versions: TI-BASIC 83 for the Z80-based TI-83 and TI-84 Plus series, TI-BASIC 89 for the Motorola 68000-based TI-89 and TI-92 series, and TI-BASIC Nspire for the ARM-based TI-Nspire series. Because it is built into every Texas Instruments graphing calculator, it is the main way a user programs one. It is an interpreted language and is considerably slower than assembly, so it suits programs that solve math problems or repeat small tasks better than games or graphics. Its syntax departs from typical BASIC, for example by assigning with a right-pointing store arrow, and programs are stored in a tokenized form rather than as plain text.
