This brings up a more general question; would someone be kind
enough to tell me exactly what the declarations "static", "private",
and "nomask" do when applied to a function, and what they do when
applied to a variable if that is different? I suspect that everyone
on this list except me knows the answer :) and if so, a reply by
email would be fine. Or, if this is in the DGD documentation somewhere
that I haven't seen it, a pointer to the appropriate file would be
fine too.

Thanks, Steve
