__SCOUT and __RCX behave as you guessed. There are also defines for __CM and __SPY for spybotics and cybermaster targets, respectively. These constants should work for BricxCC, or any other NQC environment since they are defined by the NQC compiler. (...) (23 years ago, 9-Jan-03, to lugnet.robotics)

With BrickOS, you could use the host address; which can be changed on the RCX using the view and program buttons. This would limit you to (what?) 8 or 16 RCXs, but that might be a start. // Joe (...) (23 years ago, 8-Jan-03, to lugnet.robotics)
