gsset(house.i2.r, module_type.i2.r, stanc.i1a.r, set_buffer.i1a.r,
	      event_flag.i2.r, status.i2.r [,node.i2.r])

	This routine sends a single setting (one STANC's worth) to a GAS
	speaking module.

	house		house code
	module_type	module type code
	stanc		8 byte word aligned GAS STANC
	set_buffer	buffer containing the setting data
	event_flag	event flag number to be set upon acknowledgment
			from the front end that the setting has been sent
			to a smart module
	status		status returned from the front end on acknowledgment
			of the setting request
	[node]		front end logical node number (default is TEV)

	When ready to verify the setting has been successfully sent to
	the smart module, issue call WAITFR (EFLG) and check STAT
	for success.  Only one GSREAD, GSSET, or GSLIST setup is serviced
	at a time, a reply or reply error receipt allows another GSREAD, GSSET,
	or GSLIST setup to proceed.

	The way to use this routine is:

	1) Set up arguments.
	2) Get an event flag from 'LIB_GET_EF'.  You do not have
	   to clear this event flag.
	3) Call 'gsset'.  The setting process will be initiated.
	4) Possibly do other stuff.
	5) Wait for the event flag with 'SYS_WAITFR'.
	6) Check "status".  Zero = O.K.

	Note that you ALWAYS WAIT FOR THE EVENT FLAG before checking "status".

	Note also that THE EVENT FLAG WILL ALWAYS BE SET, even if a network
	message gets lost, because we use time-outs around all network calls.

	This function requires the following include files:

	clib_h, nodedefs_h, acnet_errors_h
