When using sort to remove the duplicate records, i.e. PGM=SORT with a SYSIN containing a SORT statement and SUM FIELDS=NONE, which record will be kept?

Suppose if i have 20 records with the same key which record do you think that will be written into output. Is it first or something????

If EQUALS is in effect, then the first record of each set of duplicates will be kept. If NOEQUALS is in effect, then any record of each set of duplicates can be kept. You can specify EQUALS for DFSORT like this:

Code:

//DFSPARM DD *
   OPTION EQUALS
