X Object-reference-id-1 and object-reference-id-2 must be defined as USAGE
X OBJECT REFERENCE, with object-reference-id-1 being the receiver and
X object-reference-id-2 being the sender. If object-reference-id-1 is
X defined as an object reference of a certain class (defined as "USAGE
X OBJECT REFERENCE class-name"), object-reference-id-2 must be an object
X reference of the same class or a class derived from that class.

X If the figurative constant NULL is specified, the receiving
X object-reference-id-1 is set to the NULL value.

X If SELF is specified, the SET statement must appear in the procedure
X division of a method. In this case, object-reference-id-1 is set to refer
X to the object upon which the currently executing method was invoked.
