Input file obtained by merging 2 files

I have input file which is obtained by merging 2 files. (EACH HAVING SAY 3 REC)
The 1st four columns are as below

0001
0002
0003
0001
0002
0003

But i want the merged file to have
0001
0002
0003
0004
0005

In case we do not know the number of rec in both the input files...what can be done

You can obtain this by XSUM

Syntax for XSUM - SUM FIELDS=NONE,XSUM in the Sort card, and a DDNAME SORTXSUM to define the file for XSUM.

XSUM should be used when you have a case where the records from input file A should be copied to file B without duplicate records, and the eliminated duplicate records should be saved in a file C. Here file C will be the file for the DD name SORTXSUM.

Example:

JCL:
Code:

//STEP010 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SORTIN DD DSN=TEST.XSUM.INPUT,DISP=SHR
//SORTOUT DD DSN=TEST.XSUM.OUTPUT,DISP=SHR
//SORTXSUM DD DSN=TEST.XSUM.OUTPUT.XSUM,DISP=SHR
//SYSIN DD *
SORT FIELDS=(2,10,CH,A)
SUM FIELDS=NONE,XSUM



Input file:

Code:

0001
0002
0003
0001
0002
0003



Output: Output without duplicate:
Code:

0001
0002
0003
0004
0005


Output: Duplicate records alone (XSUM File)
Code:
0001
0002
0003
