If you explain the process (is this a match-merge, match-delete, match-compare....)
someone can help you.

there is also a 'STICKY' in the COBOL forum about reading two files in a COBOL program

Pavan101,Do you actually want to achieve this through a program, as from the description of your requirement

it looks as if it is a one time requirement.
Are there certain fields on which you want to match the records or its one record in whole u want to compare, you can use an easytrieve ,JCL sort JOINKEYS or a buch of options which Dbz has suggested.

WTF

Hello Pavan and welcome to the forum,

The best way for you to get help is to post some sample records from both files and the output you want when those exact sample records are processed. You need to identify the "keys" you want to use to compare and you need to show how duplicates should be handled as well as keys that are in one file but not the other.

Once you provide proper info, someone will be able to make a more useful suggestion.
