AMOS Basic by Francois Lionet (Europress Software, 1990) was the most popular programming language for Amiga game development by hobbyists. AMOS offered easy access to Amiga hardware: sprites, BOBs (Blitter Objects), Copper effects, scrolling, samples, MIDI — all through simple BASIC commands. The built-in editor with syntax highlighting made programming accessible. Hundreds of commercial and thousands of hobby games were created in AMOS. AMOS Pro (1992) extended it with an improved editor and compiler.
