Perl & COBOL
One way to clarify what you mean is to give EXAMPLES.
If you show a few lines from each file (names file, COBOL file), then explain what you want changed, and how the final output should look, we can help you.
We would be more inclined to help if you actually attempted to write perl code to generate the desired output, and had an actual perl-related problem with it, and explained what that issue was.
