Life Cycle of Parameterized Classes (OO Concepts for Native COBOL)

An expansion of a parameterized class is treated in all respects the same as if it were a class that is not a parameterized class.

When a parameterized class is specified in the Repository paragraph, a new class (an instance of a parameterized class) is created based on the specification of the parameterized class. This class has its own factory object and is completely separate from any other instance of the same parameterized class.

Within a run unit, two classes with the same externalized class-name that are created by expanding the same parameterized class with the same actual parameters are the same class instance. If two classes expand a parameterized class with different actual parameters, they are not the same class instance and shall not have the same externalized class-name.
