Input Definition Parameters › Overview

Overview

Input definition parameters describe input files and records and define conditions for selecting input records for processing. The three types of input definition parameters are listed below:

• INPUT (IN) parameters define the physical characteristics of input files.
• REC parameters define the physical characteristics of data fields in the input files.
• SELECT/BYPASS (SEL/BYP) parameters establish selection criteria that are applied to input records.

Each type of input definition parameter is discussed separately below, followed by examples of coding all three types of input definition parameters.
