To use a RECORD typed buffer, you must define the record in a COBOL copybook file. The copybook file includes a RECORD for each entry. The name of the RECORD corresponds to the name of the COBOL language field. For more information about COBOL copybook, please see COBOL language reference.

Below is an excerpt from an example COBOL copybook file.

$ /* copybook record */
01       CUSTOMER.
         02       NAME          PIC X(10).
         02       BALANCE       PIC S9(9) COMP-5.
         02       ADDRESS       PIC X(80).
