  Posted by Anurag - Comparing In Jcl :
How to compare two rows in a input file through a SORT Step in JCL? The compare logic should be based on comparing 1 or 2 columns of both the rows.

Guest Says:
to my knowledge sort is for sorting, not comparing files.

Jim Says:
you should use comparex as that can be run from jcl also, that way you can compare 2 files programmatically but sort probably can't do that stuff

Frank Yaeger Says:
DFSORT and DFSORT's ICETOOL offer several methods for doing comparison, matches, joins, such as JOINKEYS, SPLICE, SELECT, etc.  What you would use  depends on what you are trying to do exactly.

For examples of this kind of thing, see the "Create files with matching and non-matching records" Smart DFSORT Trick at:
