You're welcome, Tim.
At the risk of going a little off topic, now:
One thing I'd recommend to >anyone< doing this (getting large amounts of any
data off the web) is to take it easy with the amount of data you request,
how you request it and how frequently you request it. From my experience,
people are watching you use web robots, and I have seen a number of quote
servers disappear, partly because of abuse by some people excessively
accessing "free" data. Remember, there's no such thing as a free lunch -
somebody pays, somehow. That somebody always sees to be you, the user, one
way or another.
For instance, there are plenty of programs which mine Yahoo! for >all< EOD
quotes on the US exchanges. Just because you can do this doesn't mean you
should. Besides, there are other more efficient ways to get this amount of
info, without abusing Yahoo!
Please, guys and gals, don't spoil it for others - tread lightly.
Thanks for listening!
