CRU302I INVALID CATALOG RECORD LENGTH FIELD - FROM EXPIN

Explanation
 The first field in a catalog record is its length.
However, the value in this length field did not correspond to the
actual record length.

System action
 The record is dumped, the condition code is set
to 12 (if not already higher) and processing continues.

Operator response
 This condition is very unlikely and very
serious. Should it occur, you should re-execute this entire recovery
using a different (older) catalog backup. Only if this is not possible,
should you import the import the data set resulting from this job
and then give special attention to subsequent diagnostic and synchronization
checks. There will almost certainly be some errors in the recovered
catalog.
