Resolution

The ADS runtime system maintains dialog work records in storage in control blocks called RBBs and RBEs. When a dialog calls a cobol or assembler program and passes such a record to it, on return to ADS, the runtime system verifies that the RBE* eyecatcher in the control block has not been overwritten. It can do this because there is enough information in each RBE to know where the next one should start.

If it has been overwritten, message DC171068 is issued to identify the names of the involved dialog and program. The RBBs are snapped to the log, and then message DC171067 identifies the address at which ADS was expecting to see an RBE.

The most likely cause of this problem is that the program was compiled at a time when the record in the previous RBE (RECORD03 in the above example) was defined to be longer than it was at the time the dialog was compiled. Make sure that all involved programs using the same work record were compiled at times when the record had the same length.
