BTW AmigaBASIC must have been a very interesting affair too. I think Commodore's agreement with Microsoft was somehow broken after release; it was never updated, it was never really integrated into the system - Intuition, the co-processors, the famous HAM mode, etc. So it left everyone unsatisfied. And it was slow and bloated. There was a compiler for it, the AC-Basic, which I successfully used for a short while, until AmigaBASIC was literally eclipsed by AMOS.
AmigaBASIC was indeed a bit of a lame duck. I used HiSoft BASIC myself, which was backwards compatible but added a lot of features, including a compiler.
