firmdl3 doesn't work for me. Normally the rcx shows numbers up to 24 or 48, then counts back up very quickly, then after a while the program quits.There was only once where it might've worked. I also tried slow, but that stops right after mode=slow. (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.legos)

Vlad, The Finite State Machine is a good subject for people to consider in robotics, especially in coding the typical 'looping forever' Rcx applications. Lots of regular 'C' FSM's are implemented with a State variable and "switch" statements, or (...) (25 years ago, 11-Dec-99, to lugnet.robotics.rcx.nqc)
