COBOL has two ways to invoke a method: the <code>INVOKE</code> statement and inline method invocation.
<lang cobol>*> INVOKE
INVOKE FooClass "someMethod" RETURNING bar *> Factory object
INVOKE foo-instance "anotherMethod" RETURNING bar *> Instance object
*> Inline method invocation
MOVE FooClass::"someMethod" TO bar *> Factory object
MOVE foo-instance::"anotherMethod" TO bar *> Instance object</lang>
To call factory methods of objects of an unknown type (such as when you may have a subclass of the class wanted), it is necessary to get a reference to the class's factory object by calling the <code>"FactoryObject"</code> method.
<lang cobol>INVOKE foo-instance "FactoryObject" RETURNING foo-factory
*> foo-factory can be treated like a normal object reference.
INVOKE foo-factory "someMethod"</lang>
