status.i4.v = dio_is_display_short(device_index.i4.r, property.i2.r)

	status.i4.v = dio_is_display_short_c(device_index.i4.v, property.i2.v)

	This routine returns the default display length type for a device
	and property (DI/PI).
	device_index	device index
	property	property index
			(PRREAD -> reading property,
			 PRSET -> setting property)

	This function returns status values as follows:

	DIO_BADARG		invalid property index passed
	TRUE			short display format
				(DIO_SHORT_DISPLAY_LEN characters)
	FALSE			long display format
				(DIO_LONG_DISPLAY_LEN characters)

	This function requires the following include files:

	cnsparam_h, dbprops_h, diolib_h, acnet_errors_h

	Related functions:

	dio_is_display_dec(_c), dio_scaling_len(_c), dio_scaling_length_list_c,
	dio_is_string_property_c, dio_is_enumerated_property_c,
	dio_is_primary_scalable_property_c, dio_scaling,

	C/C++ usage:

	short	property = PRSET;
	int	status;
	int	device_index = 14430;

	status = dio_is_display_short_c(device_index,property);
