DIRCOMPR - PDS or PDSE Directory Compare Utility

                  © 1998-2017 GSF Software LLCr

DIRCOMPR is an MVS utility program to compare PDS and/or PDSE directories. Using DIRCOMPR, an OS/390 or z/OS installation can compare libraries for duplicate members in partitioned data sets, PDS and/or PDSE.

DIRCOMPR can compare up to 32 directories at a time and the libraries can be source and load libraries, this way you can see the existence of duplicate and location of these modules.

DIRCOMPR produces several reports, including a cross-reference of duplicate members, i.e. members found with the same name in several sub-libraries.

Running DIRCOMPR

The DIRCOMPR Utility runs as a batch job step in the MVS environment. The PARM statement gives the directive on how these libraries are compared as in the example below.

DD Statements

DIRCOMPR uses the following DD statements:

  1. SYSPRINT is used to write the reports.
  2. LIB1 through LIB32 DDs are used to describe the libraries to be compared.
