As I read this, you are saying that you want to control the buffer location
FROM THE LINKER CONTROL FILE.  (Caps for emphasis.)  Presumably, this is
because you have to tie multiple processors together, using shared memory,
and some of the processors are programmed in something other than Ada.  (If
they were all in Ada, you'd use Ada rep specs in a shared package.)

Can you do an assembly language routine, that just returns the value of an
external symbol, which will be bound by the linker, and use "pragma
interface(assembly)" to tie it together?
