Rick wanted to know how to hide a constant's value, so this is not
what he asked for. This has been answered long ago.

You mean the warning that this package does not allow a body without
this Dummy?
If you need a body, do not define junk subprograms, use pragma
Elaborate_Body instead.

package Y1 is
  pragma Elaborate_Body;
  Test_Value: Integer; -- Only initial value is hidden (if there
really is one),
                       -- it can be written by anyone.
end Y1 ;
