Hi all, Can anyone tell me if it is possible to use NQC to directly set bits in RCX registers? And if so, how does one do it? I've seen C code examples of this in a few places, but no NQC examples. Specifically, I want to turn on and off the red (...) (19 years ago, 12-Sep-05, to lugnet.robotics.rcx.nqc)
