Thanks to all who respond. After considering the suggestions, I think
I'll keep the initial proposed scheme. It doesn't follow the Ada
programming style, but is straightforward. And in some cases it can be
reduced in fact to passing the address, because the size is already an
explicit parameter in some procedures.

Thanks again,
