status.i4.v = sr_sda_num_subcases_c(usage.i1a.r, case_number.i4.v,

	This routine will return the number of subcases in an SDA case.

	usage		null terminated SDA usage string
			(SDA_USAGE_NAME_LEN characters)
	case_number	desired case number
	num_subcases	returned number of subcases
	[multiple_sets]	returned multiple sets flag
			(TRUE -> multiple sets are allowed,
			 FALSE -> mulitple sets are not allowed)
			(default is NULL)

	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, acnet_errors_h
