While their cudgels are bouncing off
your skull, they will scream the above three
lines into your swiftly swelling ears!

I suggest you write;

while True:

calculate_stuff know where to find

Hi All I'm using .getRows() with a local var array instead of doing a recursive loop so that I'm being a good ASP newvbie and closing my object i/o's (the recordset in this case) as quick as possible.
