IEBCOMPR

Its primary purpose is to compare two sequential or partitioned files. This program simply reads two files and finds out if they are identical or not.

The following is the sample of a JCL statement to execute this utility program.

//GP4ABC JOB (RR, 1235,,,,8,,U),’MR. XYZ’,CLASS=S,

// MSGCLASS=G,MSGLEVEL=1,NOTIFY=GP4ABC

//*

//***********************************************************

//* THIS PROGRAM COMPARES TWO DATASETS.

//***********************************************************

//STEP1 EXEC PGM=IEBCOMPR

//SYSPRINT DD SYSOUT=*

//SYSUT1 DD DSN=TSGBAXC.SACRED.DATA,DISP=SHR

//SYSUT2 DD DSN=TSGBAXC.NEWCOPY.DATA,

// DISP=SHR

//SYSIN DD DSN=TSGBAXC.PARMINPUT.DATA(CMPR),

// DISP=SHR

OR

//SYSIN DD *

COMPARE TYPORG= PS

or PO.

In this example, the DSN stated against DDNAME SYSUT1 and that of the DDNAME SYSUT2 are both inputs to the utility program IEBCOMPR. The program will read both the programs and will try to find similarity or dissimilarity between these two datasets and provide output to show the same. The parameter TYPORG shows what type of dataset is being compared, where PO means Partitioned datasets and PS means Physical Sequential file. This parm input can be provided to the program either in the form of a member in a PDS by stating the DSN and its member or using instream procedure by using SYSIN DD *
