status.i4.v = build_sda_case_value_c(usage.i1a.r, case_number.i4.v,
					     try_number.i4.v, case_value.s.r)

	This routine builds an SDA case value from its component values.

	usage		null terminated SDA usage string
			(SDA_USAGE_NAME_LEN characters)
			(If a value of NULL or a null string is passed for
			 this argument, the usage will be set to Collider shot.)
	case_number	case number
	subcase_number	subcase number
	try_number	try number
	case_value	returned SDA case value
			(structure of type SDA_CASE_VALUE)

	This function returns status values as follows:

	OK			success
	CLIB_NO_SUCH		no such SDA usage or case number
	CLIB_MEMFAIL		dynamic memory allocation failure
	SQL_xxx			error reading database

	This function requires the following include files:

	cbslib_h, cns_data_structs_h, acnet_errors_h

	numeric_to_ascii(_c), ascii_to_numeric(_c), input_array_values_c,

	C/C++ usage:

	static const char	usage[] = SDA_DEFAULT_USAGE;
	int	status;
	int	case_number = SDA_DEFAULT_CASE_NUMBER;
	int	subcase_number = SDA_DEFAULT_SUBCASE_NUMBER;
	int	try_number = SDA_DEFAULT_TRY_NUMBER;
	SDA_CASE_VALUE	case_value;

	status = build_sda_case_value_c(usage,case_number,subcase_number,
