RS, As Elardus kindly pointed out, you can use JOINKEYS to compare 2 different files. You have the option of comparing the keys upto 4088 bytes in Binary. In your case the input file LRECL is only 1500, so even if you wanted to compare each and every byte then you can do that. However remember that if you do happen to have duplicates in both files, then you might end up with Cartesian product is a join of every duplicate record of one file-1 to every duplicate record of another file-2. For example, if File-1 has 100 duplicate records and file-2 has 100 duplicate records then a Cartesian join will return 100,000 records. You can eliminate the dups before the match coding JNF1 and JNF2.
So If you let us know the exact requirement then we can show you how to get the desired results.
