Cause: Backward command, other than read backward, into load point on tape drive.
Programmer Action: Check for a command sequence that would cause backward motion
while the tape is at load point. Make the necessary corrections and resubmit the job.
If the problem recurs. have
· source listing
· EREP output (see DOS/VS SADP)
· log sheet
· printer output
available for problem determination.
Operator Action: See Figure 4 at the beginning of this section. Check that the tape is
actually at load point when the error occurs.
If the tape is not at load point, a hardware error is probably occurring. ln this case, issue the
ROD command, execute EREP (see DOS/VS SADP), and give the output to your programmer.
