That is only true, if you do not re-use any structure of the original program that is not part of the algorithm. If you want to be sure, you need a cleanroom re-implementation: Have someone else read the code and write down the pure algorithm. Then implement that without ever having seen the original code. https://en.wikipedia.org/wiki/Clean_room_design Best wishes, Arne -- Unpolitisch sein heißt politisch sein ohne es zu merken
