25  * A result class number is an unsigned 16 bit number.  Each class may
26  * contain up to 65536 results.  A result code is formed by adding the
27  * result number within the class to the class number multiplied by 65536.

29  * Classes < 1024 are reserved for ISC use.
30  * Result classes >= 1024 and <= 65535 are reserved for application use.
