If you use the unique or the duplicate file
I/O error values in an EGL expression, you must enable detection of
duplicate record keys for indexed files in the iSeriesC environment.
To enable this detection, you must do both of the following things:
- Define the indexed file (or its associated physical file in the
case of logical files) with the IBM® i data
description specification (DDS) language, using the UNIQUE DDS file
level keyword.
- When you generate, use a resource association part. In the resource
association entry for the indexed file, set the duplicates element
to YES. For more information, see Resource associations part.
