	status.i4.v = display_camac_crate(fe.i4.v, crate.i4.v, screen.i4.v,
					  interactive.i4.v)

	This routine draws a CAMAC crate on the graphics screen and
	displays the cards and devices associated with it.

	fe		The front end responsible for the crate.   Legal values
			are: TEV, MI, MUONFE, BOOSTR, SWYD, NUMI, TCLK, NCAMAC,
			MESON, and NEUTR.
			(constants are in 'nodedefs')
	crate		The CAMAC crate in question.  Any value between 0 and
			255 (inclusive).
	screen		The graphics screen to use.  Legal values are: GXPA_1 or
			GXPA_2.  (constants are in 'cnsparam')
	interactive	Interactive flag.
			(TRUE -> The user can click on a card and get a list
				 of devices associated with that card.
			 FALSE -> The display is static.)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		front end was not recognized
	otherwise		ACNET error code (typically a network or
				interprocess communication error)

	This function requires the following include files:

	ul_cbsaux_h:auxlib_h, nodedefs_h, cnsparam_h
