DFS2431I DBD1 `dbdname1` REFERENCES DBD2 `dbdname2` AS AN INDEX INVALIDLY

Explanation
 A DBD was referenced in an LCHILD statement in
another DBD as an index DBD. The referenced DBD was not coded as ACCESS=INDEX,
and the reference is therefore invalid.

System action
 The system issues abend 0992 if batch DL/I was
being run. ACBGEN processing continues.

Programmer response
 Correct the DBDs, and rerun the job.
