Sounds very cool, and eminently do-able. Besides the existing stepper, I had a student that started looking at integrating DrRacket's stepper with Philip Guo's "Online Python Tutor". Let me know if you want pointers to some code. John ____________________ Racket Users list: http://lists.racket-lang.org/users
