Ok, your right, there was no put_line statement.  There was only the
"put" statement.  The compiler would still have complained.

Ok, that must be why I wrote "Thus, GNAT's compiler message tells me 
not that GNAT can't determine which count to use but that I need to 
specify, for future readers, which count I needed."

Cool!  I'm going to check that out.  Thank you.

>Elaboration is nothing at all like the instantiation of a C++ class.
Ok, elaboration is like the "preparation" of something declared static 
in C++ or Java? So your saying that all the elaborations in the 
following code happen before the main procedure is called?

with
ada.text_io,
ada.integer_text_io;

use
ada.text_io,
ada.integer_text_io;

procedure newelaboration is

    procedure doelaboration(i: integer) is
        package elo is
            value: Integer;
            procedure printvalue;
        end elo;

        package body elo is
            procedure printvalue is
            begin
                put(value);
            end printvalue;
        end elo;
    
    begin
        if i < 10 then
            elo.value := i;
            doelaboration(i+1);
            elo.printvalue;
        end if;
    end doelaboration;

begin

doelaboration(1);

end newelaboration;

So using the "new" reserved word is different than an elaboration?

Thanks for the help!

Andrew
