U can compare two files by going to the ISPF menu and selecting the option of Compare( 10) from there and additionally u can set the selection criteria for recordsets that have to be compared.

File-AID/MVS has got a very powerful Compare function built-in. You can actually use you record layouts (COBOL or PL/1) and tell File-AID to compare specific fields. For example, if the 1111111 that you mentioned was a customer-id field in one file and a cust-id field in the other file, you can tell File-AID to compare the two fields, even if they are at different offsets within their respective record layouts.

The output criteria allows you to copy the entire record (from any of the input files) to another file. You are able to extract records based on whether the records matched, were deleted, were inserted or simply changed.

Once you use this compare you will never want to use the ISPF compare utility.

Good luck.
