Hi, 

i have some questions regarding bitmanipulations:

1. I found bitwise "and", "or" and "xor" operations, but as far as I 
understand they are applicable only for modular types or packed boolean 
arrays. Is this correct?


2. I did not found shift and rotate operations. Did I miss something or are 
there really none?


3. When I want treat a value both as an integer and as a boolean array, how 
can i do this? In pascal I would use a tagless record like 

TYPE ov is record
  case boolean of
    true : i : integer;
    false  : byte_array;
  end;
  end;

Such overlay structures are not valid with Ada, so what do instead?

thanks
