Hi Ken--

Does something like STATUSLINE help you? [ Assumes you are running on
an ANSI-like terminal. ] I use ANSI escape characters to control the
cursor position, so it's not portable to every type of terminal. As I
recall, I couldn't find a simply way to reposition the cursor using
FORMAT statements.
