WE CAN ELIMINATE DUPLICATES IN SORTING BY SORT UTILITY
SYNTAX IS
SORT FIELDS=(STARTING POSITING,LENGTH,TYPE,A),EQUALS
SUM FIELDS=NONE

THIS WILL SORT THE FIELDS IN ASCENDING ORDER AND ELIMINATES
ALL THE DUPLICATES, AS WE ARE GIVING 'EQUALS' IT WILL TAKE
THE FIRST RECORD AND ELIMINATES REST OF THE DUPLICATE
RECORDS IN A FILE.

Answer / muttaiah

use the Sort utility, In the instream data of the sort card
Specify.
//sysin dd *
sort fields=copy
sum fields=none,xsum
/*
for this you need to have a dd stmt as
//sortxsum dd dsn=datasetname, disp=(createnew, share)

Now, the output file will have the records without
duplicates & the duplicates will be captured in the above
dsn of the sortxsum dd.

Correct me if i'm wrong

Answer / stu

Pandu,

Answers 1 & 3 are correct. SUM FIELDS tells SORT that only
1 record with the the same values in the SORT FIELDS will be
written to the SYSOUT. SUM FIELDS=NONE tells SORT there are
no fields to SUM, but only keep one record for each distinct
combination of the sort fields.

Examples:
SORT FIELD=1,5,CH,A) SORT FIELD=1,5,CH,A)
SUM FIELDS=(7,1,ZD) SUM FIELDS=NONE,EQUALS

----+----1 ----+----1
PANDU 1 PANDU 1
PANDU 4 PANDU 4
CRAIG 3 CRAIG 3
PANDU 3 PANDU 3
HARPO 6 HARPO 6

results in
----+----1 ----+----1
CRAIG 3 CRAIG 3
HARPO 6 HARPO 6
PANDU 8 PANDU 1
