Your description is not very clear, however, it looks like you want to match/merge three files and write some output, is this what you intend to do - if not, please describe your problem again.

Compare the three files and write the output in a diff file. and have to use cobol.

well since
of item no,cost and quantity.
you don't need name in the output it is a simple 2 file match/merge.

and compare is not the term to use.
you simply want to match & merge (join) the two files.

now, if in your seriously incomplete requirements
you failed to mention that name is also required,
you have a 3 file match merge.

suggest you start by generating some pseudo-code (or flow chart) to define the process.
