	This routine will create a single latching or momentary switch
	in the window indicated by "window_id".  All switches in a window
	are automatically deleted when the window is deleted.

	window_id	window ID (use WMNGR_BACKGROUND for background window)
	type		type of switch
			(SWITCH_LATCH -> latching switch,
			 SWITCH_MOMENTARY -> momentary switch,
			 SWITCH_STATUS -> status switch which flashes like
					  a momentary switch and can have its
					  state changed programmatically like
					  a latching switch)
	row, column	window coordinates of the upper left hand
			corner of the switch (A value of WMNGR_CENTER for
			either coordinate will center the switch in the
			window for that plane.)
	height		height of switch in rows
	width		width of switch in columns
	text		null terminated switch text  (Note: For multiline
			switch labels, successive lines should be separated
			by a space which will not be displayed.)
	switch_id	returned switch ID
			(A value of NULL can be passed for this argument
			 if the switch ID is not needed.)
	[state]		initial state of the switch (only used for latching
			(SWITCH_ON -> on,
			 SWITCH_OFF -> off (default))
	[color]		switch color (default is WHITE)
			(constants are in 'cnsparam')
	[border_color]	border color (default is switch color)
			(For a status switch, this is the button press color.)
			(constants are in 'cnsparam')
	[on_func]	address of function to be called upon transition
			of the switch to an "on" state (default is NULL)
			(called as follows:
			 on_func(wid.i2.v, on_func_data.g.v, switch_data.s.r)
			 ("switch_data" is a structure of type
	[on_func_data]	address of data to be passed to "on_func"
			(default is NULL)
	[dest]		address of 4 byte integer value to be loaded
			when the state of the switch changes (default is NULL)
	[off_func]	address of function to be called when the switch
			is turned off (latching switches only) (default is NULL)
			(called as follows:
			 off_func(wid.i2.v, off_func_data.g.v, switch_data.s.r)
			 ("switch_data" is a structure of type
	[off_func_data]	address of data to be passed to "off_func"
			(default is NULL)
	[help_info]	context sensitive help callback information
			(structure of type HELP_CALLBACK_DATA)
			(default is NULL)
	[handle]	null terminated ASCII handle to be used as an
			alternate means of identifying this switch
			(default is NULL)
	[end_character]	special character to place before and after button text
			for single line swtiches
			(structure of type DELIMITER_CHARACTER_DATA)
			(default is NULL which would indicate no end characters)
			(constants are in 'extchrset')

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVARG		invalid width, height, or switch type
	CBS_NO_WINDOW		window doesn't exist
	CBS_INVSIZ		switch is too big to fit in the window
	CBS_NOT_IN_WINDOW	switch is not entirely in the requested window
	CBS_MEMFAIL		failed in allocating dynamic memory

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, cbslib_h, acnet_errors_h
