received two index points without an intervening address marker.

Operator Action: See Figure 4 at the beginning of this section. If possible, use another disk
pack or disk drive. If another disk drive is used and the failure recurs, the pack must be
re-initialized and the file rebuilt.
If the problem persists, issue the ROD command, execute EREP (see DOS/VS SADP) and have
