You might want to pack it. And you might even want to think about
your style. Here is an example:

procedure bla is

   type MATRIX is array (Positive range <>, Positive range <>) of Boolean;
   type POINTER_MATRIX is access all MATRIX;

   pragma Pack (MATRIX);

   A : POINTER_MATRIX := new MATRIX (1 .. 10000, 1 .. 5000);

begin
   null;
end bla;

I would also write the identifiers in lower-/mixedcase, now it awfully
looks like MODULA.
