Surely. But some "Paul Rubin" guy just said: "Yes, that's exactly right: the burden is moved from the application programmer to the language implementation." ...and that's exactly what's happening here. The same thing would happen in a GC implementation - they tend to be even worse because the programmers almost never consider how much garbage they are creating. And I doubt that it would be hard to add or delete data; for a program like this doing it on the fly is overkill anyway. Reading it from a file would be easy to add if you wanted to. Randy.
