Dave, I like the idea of teaching how to solve certain problems both with multiple threads and with a Finite State Machine. Adding "switch" would be great!

(...) The problem is that 1.5, does not have the vbx file to allow these to work. You have to get this from a version 1 system. (...) 1.5, adds quite a few useful pieces, but loses a few others.

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)
