detail!

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:
stuff = calculate_stuff ()
if stuff < 0.00005:
break

It may be too late though - even the
above sanitised version is still too
tightly coupled - how must
calculate_stuff know where to find
the inputs for its calculation?

You are gonna bleed!

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.

I tried one example, and am in the process of trying out more examples, increasing their complexity as I go.
