The enclosing -- subprogram does not have visibility into the nested subprogram. -- Declare and raise an exception in the nested subprogram, and allow -- the exception to propagate to the enclosing scope. Use the function -- Exception_Name in the enclosing subprogram to produce exception -- specific information when the exception is handled in an others -- handler. -- -- TEST FILES: -- -- This test depends on the following foundation code file: -- FB20A00.A -- -- -- CHANGE HISTORY: -- 06 Dec 94 SAIC ACVC 2.0 -- --! with FB20A00; -- Package containing Function Find with Ada.Exceptions; with Report; procedure CB20A02 is Seed_Number : Integer; Random_Number : Integer := 0; --=================================================================-- function Random_Number_Generator (Seed : Integer) return Integer is Result : Integer := 0; HighSeedError, Mid_Seed_Error, L_o_w_S_e_e_d_E_r_r_o_r : exception; begin -- Random_Number_Generator if (Report.Ident_Int (Seed) > 1000) then raise HighSeedError; elsif (Report.Ident_Int (Seed) > 100) then raise Mid_Seed_Error; elsif (Report.Ident_Int (Seed) > 10) then raise L_o_w_S_e_e_d_E_r_r_o_r; else Seed_Number := ((Seed_Number * 417) + 231) mod 53; Result := Seed_Number / 52; end if; return Result; end Random_Number_Generator; --=================================================================-- begin Report.Test ("CB20A02", "Check that the name " & "of a user defined exception is available " & "to an enclosing program unit even when the " & "enclosing unit has no visibility into the " & "scope where the exception is declared and " & "raised" ); High_Seed: begin -- This seed value will result in the raising of a HighSeedError -- exception.
