CAPXDBD segment type format
The IMS catalog CAPXDBD segment contains information about a Data Capture exit routine used by a DBD.
The metadata in this segment includes the name of the exit routine and processing options. Multiple DBDs can reference a single data capture exit, and a single DBD can reference multiple data capture exits. In the latter case, there are multiple child instances of this segment type for a single parent DBD segment instance.
