Compare 2 work files

Natural

What are trying to achieve? Please describe in detail.

What is the best way to compare data in two work files which have the same field present?
I want to accomplish the following:
Read work file 1 and select FIELD
Search for FIELD in work file 2
If FIELD present in both work files
Write work file 3

Do you get any error messages? Please provide a full error message screenshot and log file.

So long as the work files are sorted by the matched field(s), this can be done very easily with Sequential Match logic.

In customizing ZZMATCH, you will remove most of the comment lines and trace logic, leaving a simple, compact program.
