seqnet_send_status_message

	status.i4.v = seqnet_send_status_message(request_id.i4.v, color.i4.v,
						 options.u4.v,
						 format_string.i1a.r,
						 [,value_1, value_2, ...])

	This routine sends a status message to the Sequencer.  This message
	will be displayed in the "Messages" window of the Sequencer.  The
	calling task must be processing a request from the Sequencer at
	the time that this message is sent.  A previous call to
	seqnet_connection is required.  See seqnet_an_introduction
	for more details.

	request_id	request ID of the original request
	color		color of text message (Note: If the color is RED,
			it will be treated by the error trace routines
			and some other facilities as an error.)
			(constants are in 'cnsparam')
	options		message options (not used)
	format_string	null terminated string which contains the
			characters to be written literally or converted
			as specified by the optional value arguments
	[value_1...]	optional values which correspond to conversion
			expressions in the format string

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOINT		not currently connected to seqnet
	CBS_INVTYP		invalid request ID
	ACNET_xxx		failed to send message

	This function requires the following include files:

	seqnet_h, acnet_errors_h

	C/C++ usage:

	static const char	format_string[] = "This is a formatted error message for %F.";
	int	status;
	int	request_id;
	int	color = CYAN;
	unsigned int	options = 0;

	status = seqnet_send_status_message(request_id,color,options,
