True. So I think the best way is either to declare var q1, q2: int64; or, if they have to be qwords for some reason, to typecast: writeln(abs(int64(q1) - int64(q2))); Still, the documentation states "any numerical type". If there's time for it, FPC should imho generate a call to abs(int64) and possibly issue a warning when it encounters abs(qword). Anton ---------- Ing.
