Vincent Manis misunderstands what I want. I realize that for various reasons one cannot allow opaque types to be represented by arbitrarily large structures like arrays and records. In fact, when I teach array implementations of Tables I do it exactly as he says, with a pointer. It is the "cursor" opaque type that I am worried about; here I would like exactly what he describes - opaque types that are as big as the biggest "one-word" entity. I don't believe that this would be too wasteful of storage. Rich -------
