        !            13: GETEQUAL is used to do a keyed retrieval of a single
        !            14: tuple in cases where the calling program knows the key to
        !            15: be unique.  SETKEY must be called first to set all desired
        !            16: domain values.  GETEQUAL will return the first tuple with
        !            17: equality on all of the specified domains.
        !            18: The tuple is returned in TUPLE.
