|

Only a few minor new features, but I had to rework code generation for expressions and conditions extensively, so that's why its a beta release. (URL) Baum (24 years ago, 18-Dec-00, to lugnet.robotics.rcx.nqc)

It seems that you want to run an RCX emulator on the PC side that can use the PC IR Tower as if it was the internal transmitter in the RCX brick. Thus you could run NQC generated bytecode in your robot, and NCQ generated bytecode on your PC. I know (...) (24 years ago, 30-Nov-00, to lugnet.robotics.rcx.nqc)
