window_to_graphic_screen_c

	status.i4.v = window_to_graphic_screen_c(window_id.i2.v [,screen.i4.v]
						 [,num_rows.i4.v]
						 [,top_row.i4.v]
						 [,match_data.s.r])

	This routine allows the programmer to copy the contents of a
	TV window to one of the graphics screens.

	window_id	ID of desired window
			(WMNGR_BACKGROUND -> background window,
			 WMNGR_WHOLE_DISPLAY -> entire visible display,
			 WMNGR_ERROR_WINDOW -> error display window,
			 otherwise -> ID of desired window)
	[screen]	desired screen
			(GXPA_1 -> GXP(A/B/C) 1 (default),
			 GXPA_2 -> GXP(A/B/C) 2)
	[num_rows]	number of rows of text to display  (Note: If this
			value is defaulted or has a value of zero, the
			visible window will be displayed.  Otherwise,
			"num_rows" of the scroll buffer will be displayed.
			If this value is negative, both the visible window
			and the scroll buffer will be displayed.)
			(default is 0)
	[top_row]	top row to display (Note: This value is only used
			when displaying scroll buffer text.) (default is 1)
			(must be >= 1)
	[match_data]	text matching information which determines which lines
			will be displayed (If a value of NULL is passed for
			this argument, all requested lines will be displayed.)
			(structure of type STR_SEARCH_INFO) (default is NULL)
