Thank you, Jonas and Vincent, but I was vague: what I want is blockread'ing, so I have to use
  record
  Something: byte;
   case byte of
    1: (x,y: word);
    2: (z: longword);
  end;

Or use classes/properties (virtualization of structure: reading into memory, processing there, checking in run-time that data is accessed legally [if needed]). Should I? Is there less abstracted approach?
