If they have kept compatibility from Turbo Pascal, there is
a total casting between byte (unsigned_8), short_integer (integer_8),
word (unsigned_16), integer (integer_16), longint (integer_32)...
The bugs from unsigned <-> signed are the most vicious.
Has this changed in Delphi (read: have they "Adaized" this) ?
