I am aware of a product called RECODER that gives the following reports
on a COBOL program:

1. Warnings Report
2. Genealogy of Names Report
3. Dead Code Report
4. Structure Chart
5. Modularity Report

RECODER does Input Program Preparation, Structuring Process, Option
Dependent Code Customization, and Structured Output Generation.

RECODER is by Language Technology, Inc
	      27 Congress Street
	      Salem, MA  01970

For the record, this is a rumor.  Off the record, you might want to check
it out.
