COBOL isn't the problem, legacy systems, also, not the problem. A severe lack of oversight, and Documentation, that's the actual problem.

But its the lack of documentation and oversight that makes any of these systems unmaintainable. With Documentation, any system, no matter how old, or how obscure is maintainable.
