For example,

with Ada.Text_IO;
with System.Storage_Elements;

procedure Modular is

package Memory renames System.Storage_Elements;
package Address_IO is
   new Ada.Text_IO.Modular_IO(Memory.Integer_Address);
     
begin
   Ada.Text_IO.Put("Address of procedure Modular: ");
   Address_IO.Put(
      Item => Memory.To_Integer(Modular'Address),
      Width => 0,
      Base => 16);
   Ada.Text_IO.New_Line;
end Modular;
