Well, as Rosen pointed out, if you accept virtual memory as memory, then it's even older than that. > No, it will be equivalent to a container library. Yes, thinking more about the idea, when current S/W writes a file, it often has no idea how big that file will be until it's finished. The equivalent would seem to be a memory-mapped unbounded container that persists, with a name, after the program ends. Another thought I've had is the need to wipe non-mapped objects at program termination for security. -- Jeff Carter "Who wears beige to a bank robbery?" Take the Money and Run 144
