alt Hacker News>you can have Tk (as long as your Cobol allows you to call C).
No C required, you can just connect to the UI through a socket and often skip the FFI completely. This is my preferred way to use Tk and I don't even consider anything else unless there is a reason. Working this way also has the nice side effect of making the application UI agnostic.
But then you have an entire front end written in Tcl or some other non-COBOL language (to continue the above example,) right?
Or is there a way to run Tk as a daemon?
