Is the task one that purely uses CPU? Perhaps looping, looking at a queue for something to do, without ever waiting for anything? If so, perhaps it should issue STIMER WAIT when it detects that it has nothing to do. If, OTOH, it waits for an ECB to be posted, or an I/O to complete, or any of a number of other things, it is already relinquishing control. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
