(...) Hi Ian, Thanks for the reply. Do you know how to use the SendMessage-command from the tower? Normally if you insert this command in a Robolab-file, it will be downloaded to the RCX and executed there. Best regards, Claude (24 years ago, 25-Jan-02, to lugnet.robotics)

Hi Paula, While NQC is a nice place to start, you might want to consider LEJOS which, like legOS has its own firmware but it uses Java instead of C. It can do much more than NQC, and is quite bug free. Find out more at (URL) luck. (...) (24 years ago, 25-Jan-02, to lugnet.robotics.rcx.legos)
