6!:3 y Delay. Delay execution for y seconds. For example, 6!:3 (2.5) but today I ran into an example where that did not seem to be what it was doing. Rather than go into the full complexity of that example, let's try doing a two second delay in ten steps: delay=: 6!:3"0 timespacex 'delay 10#0.2' 3.6e_5 2432 Pretty fast right? Two seconds compressed into less than a millisecond... My guess is that J's using an api mechanism (sleep) which only supports integer seconds and it's discarding the fractions. As an alternative: Linux/OSX/etc.: nanosleep Windows: sleep (has millisecond precision) (In other words, all I really needed to do to fix this problem was switch operating systems.)
