Thank you, David. Your gode is great! I learned a lot from your quick example, though I prefer Java more. I will encapsulate RCX commands in some utility objects and use them in more higher level objects. What I focus now is make a RF/IR adapter to (...) (26 years ago, 12-Jan-00, to lugnet.robotics.rcx)

Hi Dave, On the RCX side, I wouldn't want true objects. I wouldn't want to fill up the RCX variables with vtables and the program memory with the code to use the vtables. But on the PC side of things I'm beginning to think objects can be very (...) (26 years ago, 11-Jan-00, to lugnet.robotics.rcx)
