No Garbage Collection (-nogc)

Use No Garbage Collection (-nogc) to disable automatic garbage collection of class-based objects. By default, the AVM automatically deletes .NET objects and ABL objects when there are no remaining references to the object. When -nogc is specified, the application assumes the responsibility of deleting .NET objects and ABL objects explicitly, using the DELETE OBJECT statement. If -nogc is specified, .NET objects and ABL objects that are not explicitly deleted are deleted when the session ends, and the AVM does not invoke any destructors for the class.
