GFA-Basic
GFA Basic was the most popular programming language dialect for the Atari ST. Developed by Frank Ostrowski and distributed by GFA Systemtechnik, GFA Basic quickly established itself with an ecosystem of tools, books, and libraries. The GFA Basic Editor is a modernized version with many new commands for multitasking systems.
