Nigel, thanks for the comments.  Yes, I'm sure there is things we could do
to minimize Arc/Info headaches.   Our biggest problem is that we don't keep
data long enough to really build a good structure.  We are a consulting
company and work with a variety of data structures.

I think the biggest problem we run into isn't errors over then net, it's the
speed issue.  We have serveral simulation models and amls that take forever
to run over the network.  Actually, I have an aml that you might find
interesting.  We created an aml to perform arc-arc interections.  For
example, I can take two arc covers and intersect them creating a point cover
who's attribute table is a combination of both arc covers...


regards,

Greg Zartman
