       To  initialize the routines, the routine initscr or newterm must be called
       before any of the other routines that deal with windows  and  screens  are
       used.   The  routine endwin must be called before exiting.  To get charac-
       ter-at-a-time input without echoing  (most  interactive,  screen  oriented
       programs want this), the following sequence should be used:

             initscr(); cbreak(); noecho();
