This is in fact how all OO languages actually do it, and how we did it back in the pre-OO days. We wrote object-based applications in C back in the 80s, and to do it we created "handles", which were nothing more than VOID pointers. The calling program had no idea what the pointer pointed to, but the called procedure used it as a pointer to the structure which held the "instance data" for the "object". None of this is exactly rocket science and back in the old days a decent CS teacher would explain that to you. Nowadays people look at the JVM like its some sort of magic kingdom where the laws of physics no longer apply, but the truth is it's just more code. Joe
