I started implementing this, but it's a hack.

In the case I was working with, I really did want to "jump" and retain the values, rather than restart and clear those values. Just as an aside, Rocky, I really like your ShowMeDo on pydb. Thanks for making that. (For those who haven't seen it, check out the "Introducing the pydb Debugger" at <http://showmedo.com/videos/Python>) -- http://mail.python.org/mailman/listinfo/python-list
