Surely that is obvious? I don't speak much C, but I would expect that inside the functions, const parameters can be read, but not assigned to. "*const" is a mystery to me though. > Ok, enough of C. Amen to that. If I had a dollar for every crime against computing committed because of C, or enabled due to C's design decisions, I would be rich beyond the dreams of avarice. Fortunately, C is not the only other computer language, and we are by no means limited to the two choices of the status quo (no constants in Python) and what C does. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
