Personally, I'd do something like this, as it is more explicit (you 
won't be left wondering what "magic" occurred later:

function WordToString(w: word): String;
begin
 Result := Char(hi(w)) + Char(lo(w));
end;

That's dangerous, though, if your magic number's two bytes aren't 
printable ASCII.  I believe there is an RTL function like 
IsPrintableASCII or something like that that you could check each 
character with.
