A subfile is a temporary place to store data of the same format to be used by a display file program. This allows RPG programmers to work faster and more efficiently. This guide covers the various subfile types, subfile modification, displaying multiple subfiles, data queues, and subprocedures. The CD-ROM contains the examples that can be used as template code for subfile program applications. Annotation c. Book News, Inc., Portland, OR (booknews.com)
