I haven't programmed it in decades, but IIRC it had only a few dozen steps and the only conditional jump supported was back to the start of the program? Nevertheless, I remember, that I implemented greatest common divisor and lowest common denominator programs for it. ;-)

A lot could be done by placing setup stuff in P1 and a loop in P2. I programmed it to calculate prices for flowershop things in various sizes for my girlfriend in the 90th. A full blown rule of proportion solver .
