Generally your application saves the data.  You can use a pad rather than 
a window to hold data, but that is 'limited' to 32,767 lines/columns 
(since the normal representation for the data uses a signed short).

that depends on the terminal - dialog uses special knowledge of ncurses 
and xterm to do this.
