Hello ! Being a fervent user of NQC, (thanks mr Baum!) I'm asking myself how nqc has been made. I know it's a very complex topic, but some explication for non programming-specialists could be very interesting. And because the rcx has quite limited (...)

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!

Vlad, The Finite State Machine is a good subject for people to consider in robotics, especially in coding the typical 'looping forever' Rcx applications.
