			      right_column.i4.r, bottom_row.i4.r)

	This routine will shift a window's coordinates to place them
	on the screen.  A value of TRUE will be returned if the window
	cannot fit on the screen.  Otherwise, a value of FALSE will be
	returned.

	left_column	left column of window (input/output value)
	top_row		top row of window (input/output value)
	right_column	right column of window (input/output value)
	bottom_row	bottom row of window (input/output value)

	This function returns status values as follows:

	TRUE			window is too large
	FALSE			window will fit

	This function requires the following include files:

	cnsparam_h, cbslib_h

	Related functions:

	calc_window_c, center_window_c, window_construct(_c),
	window_create(_c), window_fit_window_c, window_unfit_window

	C/C++ usage:

	int	too_big;
	int	left_column = 1;
	int	top_row = 5;
	int	right_column = 10;
	int	bottom_row = 9;

	too_big = shftwn(&left_column,&top_row,&right_column,&bottom_row);
