ANY suspend()
This function suspends the current task indefinitely. A suspended task is resumed by calling the function (in another task) resume(). The return value of suspend is given as the second argument to resume(). If no second argument is given, the return value of suspend() is zero. See Frames and Tasks for more information on task control.
