status.i4.v = dio_digital_control_list_c(list_id.i4.v,
						 string.i1a.r, length.i4.v,

	This routine sends a digital control command to a list of devices.

	list_id		list ID returned from a previous call to
			dio_bld_set(_c) or dio_bld_set_raw(_c)
	string		digital control string
	length		length of string (If a value of zero is passed,
			the length of the string will be calculated.)
	errors		array of returned ACNET status values

	This function returns ACNET status values as follows:

	OK			success
	DIO_MEMFAIL		memory allocation failure
	DIO_NOLIST		requested list does not exist
	DIO_BADARG		invalid digital control string
	DIO_SETDIS		DIO settings are disabled
	negative value		ACNET format error indicating overall failure
	positive value		number of devices in error indicating partial

	This function requires the following include files:

	diolib_h, acnet_errors_h

	C/C++ usage:

	static const char	string[] = "Reset";
	short	errors[2];
	int	status;
	int	length = 0;

	status = dio_digital_control_list_c(list_id,string,length,errors);
