(...) What is in a "counter loop iteration" ? Please share the NQC program you used to measure this with us. I fail to believe that a simple loop runs this slow. 16000 cycles per loop iteration does not sound right to me. -Kekoa (25 years ago, 4-Jan-00, to lugnet.robotics.rcx)

I'm not sure if the terminology from LEGO is "direct" or "immediate" commands, but either way the idea is that some of the bytecodes can be sent to the RCX and the RCX will execute them immediately.
