Hello,

Do you have "keys" to match or are you trying to compare the entire record?

Please post an example of the data in your input files and what you want as output from that input.

My requirement is :

Hello,

First sort both files by the "key".

Next, code a 2-file match/merge or use the matching capability of easytrieve (ther are multiple previous posts in the forum).

If you do not know how to write a 2-file match/merge, there is a "Sticky" near the top of the COBOL section of the forum that you can use as pseudo-code. Or, you can simply download the sample code and use it.

I would recommend using DFSORT for this, and the topic is well discussed in that forum with good examples too.
