  AW: C++ pointer to byte array --> Delphi

  I think in Delphi the upcast is done automatically by the compiler when the result is stored in a variable that is bigger than the operands.
  
  
  var
  b: Byte;
  i: integer;
  begin
  b := 255;
  i := b shl 2;
  // i should now hold the value 510

  I am not sure what you mean by that sentence, "whare" was not a word last time I checked ;).
  
  I assume you wanted to say that the typecasts are unnecessary, which may be true. I didn't examine the code that closely, I was just saying that you should pay attention to that.

  Looks mostly good to me, but I would pay some extra attention to the type casts. I am not sure if ord() always gives the correct result here. In some places the type cast might be done to truncate a value. For example, (ushort)foo gives us the lowest 16 bits of foo.
  
  And in the top code, I think you can get rid of ord() entirely, if you've correctly translated char as byte.
