Hi Robert: (1) Things are not that simple. In fact in setting up a run, extensive database backup is already involved. Subsequently, data structures are built at runtime of typically 0.5Gbytes. Although saving this should work, it would require quite some debug/verification to check out the validity. Many data structures intervene. Dennis' suggestion worked fine so I'm happy to be able to leave everything else 'untouched'.
(2) As to your VB question. I have been 'forced' to do a lot of VB related to M$ Access db work. VB is 100% integrated in M$'s Visual IDE and allows you to change 'on the fly' almost anything in the code, even in the midst of a debug breakpoint stop. This is very, very handy. It would be a very valuable addition to Python, though it's not very clear to me how this could be implemented without a specific IDE. (Don't switch to VB for this though. Python is much cooler). -- http://mail.python.org/mailman/listinfo/python-list
