I did COBOL for two years out of college. It is the most frustrating and terrible language to work in. We weren't using it on a mainframe we were using it to build GUI apps that run on client machines. I would spend days writing code that would take 20 minutes in c#.There were 10k line files with all global variables and you might think it was just bad design and what not but the team was very disciplined and focused on quality. There are no tests, documentation or Google queries to help you. Your job is to dig in an enormous codebase to understand what it does and that is tough. The developer output compared to a modern language is tiny compared to a Java or .NET developer.
