I have 2 files. The files have duplicate records.

I have to compare both the files and then get the records which match. Then I write the matched records into the O/P file.

I think we have to use the INREC option along with SORT but I do not know how it works !

E.G

Code:
File 1:-                           File 2:-

1                                   4
1                                   3
2                                   3
3                                   1

O/P is :-

1
3


Can anyone let me know how Inrec option here would be helpful and can also please suggest some other logic for this requirement !

Here's a DFSORT/ICETOOL job that will do what you asked for. It doesn't use INREC.

Code:

//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DSN=...  input file1
//IN2 DD DSN=...  input file2
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//OUT DD DSN=...  output file
//TOOLIN DD *
* Eliminate dups from IN1
SELECT FROM(IN1) TO(T1) ON(1,1,CH) FIRST
* Eliminate dups from IN2
SELECT FROM(IN2) TO(T1) ON(1,1,CH) FIRST
* Get matching records from IN1/IN2
SELECT FROM(T1) TO(OUT) ON(1,1,CH) FIRSTDUP

If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:
