I suppose IBM's XEDIT is not what you're looking for?

This is the way everything works on IBM terminals.  The terminal has
a data entry region which you fiddle with using the editing keys on
the terminal, you then hit the ENTER key (different from return) to
send in the edited line.  IBM's XEDIT editor is a powerful interactive
editor (albeit completely different from EMACS) which allows further
operations on the file.
