Editing Copybooks with Syntax Errors
The Copybook Source Editor contains visual indicators that help you locate syntax errors within the copybook.
If errors in the copybook source are present that could disable the client operation mappings, you will be prompted to OK the procedure before you can continue. When you remove errors from the copybook, the host transaction is repaired, but you must always manually update the client operation.
Because the copybook reflects the underlying COMMAREA or Message I/O area of the host program, it is difficult to validate the contents of the copybook. Make sure the final layout of the copybook that will be used by the host transaction matches the COMMAREA.
