It is hard to tell without looking at the context what the best solution 
is. If the string is fairly local then an access type can probably be 
used without worrying too much about creating leak by doing something 
based on....

type Access_String is access String;
procedure Free is new Unchecked_Deallocation(String, Access_String);

..
..
.. code that is getting N

begin
   Region_Data := new String(1 .. N);
   Fill_In_Data_Into_Region_Data

   Call_Existing_Code_THat_Wants_String(Region_Data.all);

   Free(Region_Data);

exceptioon
   when others =>
      Free(Region_Data);
      raise;
end;
