First Read the Ada manual:
Then on uour specific question
It is a mater of scope so have a look at the folowing:

procedure main is
    V_main_1 : integer := 0;

    procedure s1 is
        v_s1_1 : integer := 0;
   begin
        null; -- V_main_1 and V_s1_1 is vissible here;
    end;

begin --main
    declare
        V_Main_2 : integer := 0;
    begin
        null; -- V_main_1, V_main_2 and V_s1_1 is vissible here;
    end;
    --     V_main_1 is vissible here;
end main;
So think of it as a tree wher the main trunk is the "main" procedure and all
branches will see back towards the main trunk
but not other branches.
