It is only a personal preference, not a serious problem.

I would find code in the form of
   ArrayLen := IncLength(ArrayName, 1);

to be much more readable then

    SetLength(ArrayName, Length(ArrayName)+1);
    ArrayLen:= High(ArrayName);

I was just hoping somebody may know how its done.

Thanks - SteveG
