Definition of 0P33


Cause: A parity error has been encountered in one of the buffers on SYSxxx.
If the device is a 1403, 5203, or 3203, the UCB is in error.
If the device is a 3211:
· the UCB is in error if byte 1 of SNS=X'80'
· the FCB is in error if byte 1 of SNS=X’10'
· both buffers are in error if byte 1 of SNS=X'90'
In all these cases the buffer must be reloaded before the device is used again.
If the device is a 3211 and SNS does not equal X'10', X'80', or X'90', the UCB is in error, but
operations may be continued with printer speed reduced.
This is probably a hardware error.
Programmer Action: none.
Operator Action: See Figure 4 at the beginning of this section. The applicable buffer must be
If the problem recurs, issue the ROD command, execute EREP (see DOS/VS SADP), and have
the output available for problem determination.
