If you're using Windows, you can watch your programs variables with Rcx Command center. It wouldn't be hard to write a variable watcher for other platforms either. This doesn't cover all debugging sessions but I find it helps a lot. Mike Kory Georg (...) (25 years ago, 30-Jan-00, to lugnet.robotics.rcx.nqc)
