You can use a PAD object for this. PADs are basically windows which
are of arbitrary size (i.e. can be bigger than the screen). PADs are
used together with a WINDOW, where the window acts as a viewport. They
take some getting used to (and a lot of experimentation), but they
would do nicely for what you want, i think.

"curses" is synonymous with "much struggle" ;).

i can't answer anything about the forms - i've never used the ncurses
forms/menu parts.
