I've written code that uses dirty tricks like that to avoid duplication. It's at least as much of a problem as actual duplication is. Generally, the 'goto' solution results in subsequent programmers (such as my future selves) staring at the code for 30-60 seconds to figure out what it's doing. I don't like to do that to myself, much less to people I actually admire and respect. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
