Dean,
Well, that was the problem...changing the 10000 to 100 makes me get a value

effectively..I'll probably have to learn legOS so I can use floating-point
and get more precise values.
Thanks for your help,
Jeff

| Jeff, Your problem is with the 16 bit integer size that NQC uses. All integers are in the range -32768 to 32767. Using 10000 to simulate fixed point math operations is killing you. Everything works when you replace theta and D with constants because (...) (21 years ago, 2-Feb-03, to lugnet.robotics.rcx.nqc)
