Eric, thanks for pointing out several mathematical oops.
I'm still getting used to ALL of these things. I'm really doing
things ground up.
Robert, I'm sure this has all been done before.
How terrible is the assume database?
Having it for the type of use I used it for is great.
I'm sure there would be a huge amount of work to make solve use
it, so thanks for being clear about that.
Sorry for the noise
