(...) 256 * 128 = 32768, one higher as the biggest positive integer value. The cast to long would help, but your cast is too late.

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. (...) (23 years ago, 25-Jan-02, to lugnet.robotics.rcx.legos)
