	status.i4.v = dio_display_attributes_c(device_indices.i4a.r,
					       properties.i2a.r,
					       display_lengths.i4a.r,
					       display_types.i4a.r,
					       errors.i2a.r
					       [,num_devices.i4.v]
					       [,options.u4.v])

	This routine returns default device value display attributes for
	a device or list of devices.
	
	device_indices	device index or array of device indices
	properties	property index or array of property indices
			(PRREAD -> reading property,
			 PRSET -> setting property)
			(If the first value is less than zero, all devices
			 use a property index which is equal to the absolute
			 value of this argument.)
	display_lengths	returned default display lengths
			(DIO_SHORT_DISPLAY_LEN or DIO_LONG_DISPLAY_LEN
			 characters unless the common transform is a
			 special string scaling transform (60 or 84)
			 in which case the length is determined by the
			 conversion type specified in constant 0)
			(A value of NULL may be passed if no display lengths
			 are needed.)
	display_types	returned default display types
			(DIO_STANDARD_NOTATION -> display values in standard
						  notation,
			 DIO_SCIENTIFIC_NOTATION -> display values in
						    scientific notation)
			(A value of NULL may be passed if no display types
			 are needed.)
	errors		returned ACNET status value or array of returned
			status values (A status of DBM_NOREC indicates that
			the requested PDB does not exist.)
	[num_devices]	number of devices in list
			(default is 1)
	[options]	scaling options
			(DIO_DISPLAY_OPT_NONE -> no options selected (default),
			 DIO_DISPLAY_OPT_LONG_TEXT -> request long text for
						      devices which have both
						      short and long text
						      options)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid property index or number of devices
				passed
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error
	positive value		number of devices in error

	This function requires the following include files:

	dbprops_h, diolib_h, acnet_errors_h

	dio_display_conversion_info_c, dio_display_conversion_type_c,

	C/C++ usage:

	short	errors[NUM_DEVICES];
	short	properties = -PRSET;
	int	status;
	static const int	device_indices[NUM_DEVICES] = {14430, 14431};
	int	display_lengths[NUM_DEVICES];
	int	display_types[NUM_DEVICES];
	int	num_devices = NUM_DEVICES;
	unsigned int	options = DIO_DISPLAY_OPT_LONG_TEXT;

	status = dio_display_attributes_c(device_indices,&properties,
					  display_lengths,display_types,
					  errors,num_devices,options);
