If AUDIT finds the TTOC base record, it checks the sequence of
CDDs against the sequence of TTOC entries found in the base record
and zero or more TTOC extensions. If a TTOC extension is missing,
AUDIT reports *ERR 111.
For a CDD with a corresponding data set record in the BCDS:
- If the block count in the previous TTOC
entry does not agree with the number of blocks read since the previous CDD has been found, AUDIT reports *ERR 135.
- If the data set record refers to a backup version record for the
current position on the tape, but the corresponding TTOC entry is
flagged invalid, AUDIT reports *ERR 136.
At the end of the volume:
- If the valid block count in the TTOC does not agree with the number
of valid blocks read, AUDIT reports *ERR 137.
- If the total block count in the TTOC does not agree with the total
number of blocks read, AUDIT reports *ERR 138.
