Using the MODE Parameter Each User Logging intrinsic includes a mode parameter used to indicate whether the I/O is to be performed with WAIT or NOWAIT. If NOWAIT is specified and the User Logging process is busy with a long operation (for example, allocation of disc space or writing a block to tape, etc.) and cannot accept data, an error will be returned and the operation should be attempted again. If WAIT is specified and the User Logging process is busy, the intrinsic will return to its caller only after the User Logging process becomes available and the I/O completes. WRITELOG allows a third value for the mode parameter, WRITE-and-FLUSH, which causes the User Logging buffer to be flushed at the first opportunity.
