(...) NXC is something like NQC and it is available for Windows, Mac OS X, and Linux platforms. While NXC is not yet complete, it is very functional with a large API for the NXT.

(...) Here is a simple multi-threaded NQC program: task music() { while (true) { PlayTone(262,40); Wait(50); PlayTone(294,40); Wait(50); PlayTone(330,40); Wait(50); PlayTone(294,40); Wait(50); } } task main() { start music; while(true) { (...) (18 years ago, 9-Jan-07, to lugnet.robotics)

(...) Thanks John - quite clear now. Though I still don't understand why there are 2 different opcodes that can be used for more or less the same thing??? Philo (18 years ago, 9-Jan-07, to lugnet.robotics)
