Review for a HANDLE command in the program. If so, replicate the HANDLE line and comment out the original line.
From the replicated line, remove any path for a data exception off of the HANDLE command line (i.e., data check (DCK), program check (ASRA), or run-time error (RTE)). ASRA, DCK and RTE are the current data exception paths for a HANDLE command; however, in the future there may be others.
As such, refer to the CA Gener/OL Reference Manual under the topic HANDLE Command.
Rerun the program. You should then get the error messages for a data exception, which will tell you the line the data exception occurred, the field name and the bad data. Correct the field(s) in question.
