Use MATCH FILE processing with OLD-OR-NEW results.

If you don't know MATCH then you should be able to see a manual in the Tech Documentation link above.

Here is an outline to get you started. You should read up on each topic in the documentation,

1. Write a master file for each csv file of type COM. You may need to put a $ at the end of every line, or use SET PCOMMA=ON.
2. Either read up on MATCH file syntax (easiest)or hold one or both tables as Format FOCUS with an index on combined key columns and then JOIN them together.
3. The MATCH file will have BYs on the key columns. AFTER MATCH HOLD OLD-AND-NEW. Or if JOIN, inner join on the combined key fields.
4. Print the hold file from the match, or from the join.
