Answer / vivek c

A simple way to take the matching records if there are no duplicates in both the files.

1. Merge both the files and take the duplicates in separate file using XSUM.

//S010 EXEC PGM=SORT
//SORTIN DD DSN=DSN1
// DD DSN=DSN2
//SORTOUT DD DSN=DSNOUT
//XSUM DD DSN=DSN.MATCH
//SYSIN DD *
SORT FIELDS=(1,1,CH,A)
SUM FIELDS=NONE,XSUM

The output DSN.MATCH will have the matched records.

Answer / harsha

Use following JCL
//STEP010 EXEC PGM=ICETOOL
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//FILEIN DD DSN=XXXXXXXXXXXXXX,DISP=SHR
//TOOLIN DD *
SELECT FROM(FILEIN) TO(UNIQFL) -
ON(1,73,CH) NODUPS
SELECT FROM(FILEIN) TO(DUPFL) -
ON(1,73,CH) ALLDUPS
/*
//*
//DUPFL DD SYSOUT=*
//UNIQFL DD SYSOUT=*
//*

Label DUPFL will show all duplicate records
Label UNIQFL will show all unique records

Answer / leo

Using matching logic:

perform following code until either of EOF is found.

EVALUATE TRUE

WHEN KEY1> KEY2
READ FILE2
WHEN KEY2> KEY1
READ FILE1
WHEN KEY1=KEY2
WRITE FILE3 (WHATEVER FORMAT YOU WANT)
READ FILE1
READ FILE 2

END-EVALUATE

You can perform above code until both EOF found, incase you
need to create another file for non matching records. for
matching records only performing until either of EOF will
work.
