Hi I have a light-seeker NQC program for RCX, I want to port for Scout, does anyone know how to do it? Then does Scout use external light sensor? BR Zhengrong (24 years ago, 15-Aug-00, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)

Your program is pretty difficult for me to follow...way too many tasks starting and stoping one another.
