  Function       Sets the default cursor mode to be used by makewindow.
  Syntax         void setcursordefault( int cursormode );
  Remarks        This routine simply assigns a value to the global variable
                 cursordefault.  This value is already assigned by initwindow
                 to the current cursor mode.  If a specific cursor mode is
                 required for the initial window as well, use setcursor
                 instead before initwindow.
  Return value   None.
