window_message_create_c

	status.i4.v = window_message_create_c(top_row.i4.v, left_column.i4.v,
					      overall_message.i1a.r,
					      overall_color.i4.v,
					      message.i1a.r, message_color.i4.v,
					      message_id.i2.r)

	This routine will display a single line message window.  It supports
	both an overall message which will appear in the title of the window
	as well as a more explicit message in the body of the window.  Both
	text strings should be null terminated.  The message in the body
	of the window can be changed by calls to window_message_update_c.
	The message window will remain until it is deleted by a call to
	window_message_delete_c.

	top_row		top row of window
			(use WMNGR_CENTER for centering or WINDOW_xxx_COORD
			 macros in 'macro' for special positioning)
	left_column	left column of window
			(use WMNGR_CENTER for centering or WINDOW_xxx_COORD
			 macros in 'macro' for special positioning)
	overall_message	overall message for the title of the window
			(must be null terminated)
	overall_color	color of overall title message
			(constants are in 'cnsparam')
	message		first message to be displayed (must be null terminated)
	message_color	message color
			(constants are in 'cnsparam')
	message_id	returned ID which can be used in future calls to
			window_message_update_c or window_message_delete_c

	This function returns ACNET status values as follows:

	OK			success

	int	status;
	int	top_row = TOP_ROW;
