Hi Doug,
copied and pasted, thanks
although my reason for the die() was that I've started using Python to
do DB maintenance. I find it very handy (ie IDLE) and the DB api's for
all the different DB's I work with are nice and standardized (PHP could
learn a thing there). One thing that has happened, though, is that I've
clicked (via Winders Explorer) on a .py to open it for edit only to it
have run, which is not what I want when the code could start modifying
data. Thus far it hasn't caused any damage. So my safety check is to
do a raw_input from a commonly included module which does the sys.exit()
if running the code is not desired.
A basic safety catch.
