Could someone explain to me how you use the kernal functions: sleep(word que, long cond) and... wake(word que, long cond) I'm sure they're really usefull, but in both the Atari ocmpendium and the MiNT documentation, the explanation is simply 'sleep/wake a process waiting for condition 'cond' on que 'que'' which isn't very helpful. What are valid values for 'que' and 'cond'? Cheers, James.
