I think I know what these numbers are. Look like Integer'first.

But I wanted to see the range of
the first dimension of the Matrix A below. (1..3, 1..3)

----------------------------------
with Ada.Text_Io; use Ada.Text_Io;
with Ada.Float_Text_Io; use Ada.Float_Text_Io;
with Ada.integer_Text_Io; use Ada.integer_Text_Io;
with Ada.Numerics.Real_Arrays;  use Ada.Numerics.Real_Arrays;

procedure foo1 is
      A : constant Real_Matrix :=
               (( 1.0,  2.0,  3.0),
                ( 4.0,  5.0,  6.0),
                ( 7.0,  8.0,  9.0));
begin

      put(A'First(1)); new_line;
      put(A'Last(1));
          
end foo1;
-------------------------------

I think I Will go hunt for a book on Ada, and will
look at the packages Dmitry just posted.

thanks,
