Hi,
How to extract non duplicte records from a file thru sort?
If we use SUM FIELDS=NONE, The result will contain one record of the duplicates. My requirement is to extract only non duplicate records ie if duplicate is there for a record then that record should not be there in the output.
Thanks,
raam |

Hi,
I'm sure there are many examples in the forum, but it's Friday afternoon
and in a good mood
here is an example
| Code: |
//STEP0001 EXEC PGM=SYNCTOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD *
1
1
2
//NODUPS DD SYSOUT=*
//TOOLIN DD *
SELECT FROM(IN) TO(NODUPS) ON(1,1,CH) NODUPS
/*

| And if you are looking for something else (and not the one which Gerry has shown which is actually in the close proximity per the problem description); please post some sample input, expected output along with their LRECL & RECFM. |

Raam,
I have used the same condition SUM FIELDS=NONE using SYNCSORT utility and its working fine for me.

If a Dataset has 22
22 as input
then output will be 22 if we use the above condition |

Try this SyncSort for z/OS 1.3 application:
| Code: |
//SORT EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTOUT DD SYSOUT=*
//SORTIN DD *
AAAAA
BBBBB
CCCCC
DDDDD
AAAAA
CCCCC
//SYSIN DD *
INREC FIELDS=(1:C'001',1,5)
SORT FIELDS=(4,5,CH,A)
DUPKEYS SUM=(1,3,ZD)
OUTFIL OUTREC=(1:4,5),INCLUDE=(1,3,CH,EQ,C'001')
