Discussion This routine writes the given byte value to the specified queue. If there is insufficient space in the queue, the calling task will suspend until space becomes available. This means that if data is never taken out of the queue thus making room for additional data, the process will never complete. Note that before any queue operations are performed, the queue data structure must be initialized. See the discussion of OpenQueue() for more details. Also, attempting to put data in a queue that has been assigned to a Com port as the receive queue will produce undefined results. Example Dim outQueue(1 to 40) as Byte Call OpenQueue(outQueue, SizeOf(outQueue)) Call PutQueueByte(outQueue, &H55) Compatibility This routine is not available in BasicX compatibility mode.
