IEBCOMPR Utility

IEBCOMPR utility is used to

• Compare two PS (Physical Sequential) Datasets
• Compare two PDS (Partitioned Data Set)/PDSE (Partitioned Data Set Extended)

If we want to compare two PS files using this utility, both must have same record length. 

Ex. Comparing two PS files

//STEP1  EXEC PGM=IEBCOMPR
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=PSFILE1,DISP=SHR
//SYSUT2 DD DSN=PSFILE2,DISP=SHR
//SYSIN   DD *
  COMPARE TYPORG=PS
/*

The two PS files which are to be compared must be given in SYSUT1 and SYSUT2

COMPARE TYPORG=PS specifies that the input data sets are PS files.

If they are PDS/PDSE files, then we should give COMPARE TYPORG=PO

Ex. Comparing two PDS files

//STEP1  EXEC PGM=IEBCOMPR
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=PDSFILE1,DISP=SHR
//SYSUT2 DD DSN=PDSFILE2,DISP=SHR
//SYSIN   DD *
  COMPARE TYPORG=PO
