To edit output for externally described files, place the edit codes in data description specifications (DDS), instead of in RPG IV specifications. See the iSeries Information Center database and file systems category for information on how to specify edit codes in the data description specifications. However, if an externally described file, which has an edit code specified, is to be written out as a program described output file, you must specify editing in the output specifications. In this case, any edit codes in the data description specifications are ignored.
