To create a CICS COMMAREA-based operation

  1. In the Interface Mapper, right-click Operation, and click New.
  2. Define the new operation by specifying:
    • A name for the new operation
    • A program
    • An input data area, which you select from the list of COMMAREAs available in the program
    • An output data area, which you select from the list of COMMAREAs available in the program
    • Any user exits that you require
  3. If you want to automatically create interface fields with default mappings for all of the fields in the input and output data areas, check Create Default Mapping.
