	in_box.i4.v = winboxc(window_id.i2.r, top_row.i4.v, num_rows.i4.v,
			      left_column.i4.v, num_columns.i4.v)

	This routine will return a value of TRUE if the TV cursor was in
	a specified box in the indicated window the last time the
	window_intype routine was called.  The box is specified by a
	starting row inside the window ("top_row"), a number of rows
	("num_rows"), a starting column inside the window ("left_column")
	and a number of columns ("num_columns").  The top left character
	inside the window border is row 1, column 1.  The top left character
	of a borderless window is row 0, column 0.

	window_id	window ID
	top_row		top row of box
	num_rows	number of rows in box
	left_column	left column of box
	num_columns	number of columns in box
