I've recently started messing with a little cobol, the "display/accept" screen creation is really quite a nice method of developing a TUI. It can be made amazingly quickly and changed quicker than most apps (See https://wmealing.github.io/simple-cobol-query.html for example).

The GNUcobol implementation doesn't seem to support UTF-8 characters, that'd be awesome if it did, preventing even more awesome "screen/accept" input screens.

My big beef that I have with the language is that there is third party "extensions" built right into the language, which is very frustrating when trying to understand as a new user.
