I forgot one IMPORTANT detail:
DON'T USE the AGC() (change the name in the sources because I misspelled it) as control in cycles because NQC is not compatible with it, assign it to a variable instead.
For example, don't do things like this:
repeat( AGC() )
{
[...]
}
Do this instead:
a = AGC();
repeat( a )
{
[...]
}
By the way, if you find an use for the AGC() let me know :-)

| Your program generates a .RCX file of 440 bytes. I've created one with 452 that works OK, but had to stop around that number because after more 2 or 3 lines of code the last task simply disappeared (my program had 1 main plus 3 tasks). I guess the (...) (26 years ago, 28-Nov-98, to lugnet.robotics)
