need a simple, easy-to-use, unix-based editor with on-line help

[steve.j.alesch]

I'm developing a system which will  use  a  character-based  user
interface  (not  a graphical user interface, at least initially).
The intended user is not required to have any computer  literacy.
They  will  be  presented  menus  and  just  type  in  one or two
character commands as they work their way thru the menus.   In  a
couple  of situations I will need to have the user use an editor.
Vi or emacs are much too complicated for this type of user.  Does
anyone  know of a simple, easy-to-use, unix-based editor that has
on-line help that I could use for such a system?

The target system is an AT&T 3B2/500 running UNIX System V R3.
