Addressing

• Classes are addressed by a source qualification: S=<class>, where <class> is the name specified in the CLASS-ID paragraph.

• Methods are addressed by a procedure qualification, where <method> is the name specified in the METHOD-ID paragraph:

  PROC={FACTORY | OBJECT}.PROC=<method>

  A source qualification is required whenever the current program location is not in (a method of) the class.
  Procedure qualifications are only needed to the extent required for unique identification. Consequently, PROC={FACTORY | OBJECT} can always be dropped for methods, since the method name must be unique in the class.
