TI BASIC is a now discontinued ANSI-compliant implementation of the BASIC programming language interpreter for the Texas Instruments TI-99/4 Home Computer (1979), developed at Microsoft by Bob Wallace and Bob Greenberg. A version supporting compiled code was also used as a commercial development language for the TI-990 range of minicomputers.
