Supoose i am using JCL Sort Technique
using SUM FIELDS=NONE, Which eliminated Duplicates.

With DFSORT, if EQUALS is in effect, the first record of duplicates will be removed. If NOEQUALS is in effect, any record of duplicates can be removed. If you want to guarantee that the first record of duplicates will be removed, specify:

Code:

    OPTION EQUALS


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:
