Parameterized Interfaces (OO Concepts for Native COBOL)

A parameterized interface is a generic or skeleton interface, which has formal parameters that will be replaced by one or more class-names or interface-names. When it is expanded by substituting specific class-names or interface-names as actual parameters, an interface is created that functions as a non-parameterized interface. See the ACTUAL-PARAMS Compiler directive for details of this expansion.

The life cycle for a parameterized interface is defined in the section Life Cycle of Parameterized Interfaces.
