Hello Tom, I used Claude. As an experiment, I expanded a program of over 800 lines with an additional function, and it was also perfectly modified in 30 seconds. The big advantage of my test is that I can verify that it ultimately works correctly. Otherwise, the warning Claude gives, that it doesn't test for correctness, is appropriate. regards Hans
