The interpreted language that I implemented is a mix of the worst of
several other languages.  The best description is TinyBASIC with RPN
expressions.  It was designed for speed, not elegance.  You wouldn't
want to write a program longer than 20 lines.

This evening I needed to make the ECM hardware enter and leave limp-home
mode at about 1 Hz.  30 seconds and a 7 line program later, it was doing that.
