The Display file is created by the EXTRACT phase and is input to the DISPLAY phase. It contains selected before and after images from the Archive Journal file. Normally, the Display file is of a transient nature (passed from the MAIN phase to the DISPLAY phase and then released); however, the Display file can be kept for your own special reporting requirements.
The display record is a variable-length record composed of an 84-byte sort header and a database record image. A 4-byte segment (record descriptor word - RDW) physically precedes each display record but is logically transparent to COBOL programs.
