Notes
Object class(es) are automatically registered when a dynamic load library containing an object definition is invoked.
The only advantage of deregistering an object is to improve system performance.
All registered classes are maintained in Interface Repository. Some classes has its representation in OS2.INI and are cached upon system initialization. Should a class not be needed it should be removed.
