                  - If a data-item is declared in the Object-Storage Section of a class object, it is class data. Class data may be referenced
                     only in class methods. Class data can be inherited by subclasses. 
                     	 
                  
- Data is in its initial state at the start of the run unit and remains in its last used state between method invocations.
