BASIC and its extensions
The well-known foundation of programming on the TI-99/4A were the built-in TI BASIC and the cartridge-based TI Extended BASIC
There were many third-party extensions of TI Extended BASIC.
- Mechatronics Extended BASIC II+ incorporated the APESOFT Expanded Graphics routines into their version of the cartridge.
- Triton included many additional commands in their Super Extended BASIC
- Winfried Winkler included many additional commands in Extended BASIC III (in extremely limited release by Asgard, but generally only available as a set of files for the HSGPL card)
- Myarc Extended BASIC II included many of the commands originally planned for inclusion in TI Extended BASIC II (as seen on the TI-99/8)
