Cross Reference Processor

Cross Reference Processor

Tracks all references to data items

The Cross Reference Processor analyzes a collection of data usage files to track all references to data elements throughout a system of COBOL programs. Control statements assign a descriptive title to each subset of records to be reported together (most commonly a file), specify the 01-level records that are to be associated with each title, and specify processing options.

Output

Output form this module are two reports that provide extensive cross-reference information about the system of programs: the System Data Cross-Reference Report and the Dictionary of Data Names Report. These reports aid in developing control statements for the DDDL Generator.
