Use a modular integer type to get the XOR operation:
-- begin example
procedure Show_Xor
is
type Unsigned_Byte_T is mod 256;
x, y, z : Unsigned_Byte_T;
begin
x := 26;
y := 33;
z := x xor y;
end Show_Xor;
--end example
If you also want shift and rotate operations, start from the types
defined in the Interfaces package, such as Interfaces.Unsigned_8 and
other sizes.
