Dear Listers,

Is it not possible what I wanted to get done? Do I need to write a program to do it?

I believe that you would do well to search this forum for "OVERLAY".

And be patient - you posted in the middle of the night for me and others. We all have real jobs to do that take priority over helping (or otherwise) in the forum. If you want 'quick' then search, read or pay.

And you have not given an example of your desired output. And...will bith your files have only 1 record? And...if multiple records how are they matched? Are there duplicates? etc etc eg. LRECL and RECFM

Hi Nic,

The output will be a third file (LRECL=80) -

how many records are in each file?

what are the matching columns?

Hi Dick,

Each file contains one record and there both the files have the first four characters the same. Hence we can match on those.
