Hi Mike

You wanted others to jump in. I am not doing that, this will be my only comment (I hope <g>).

I am also a lover of VFP and DBF's, and I agree with you that you can do most things with VFP and DBF tables. But to be realistic, when you for instance talk about BIIIG amounts of data, or with MANY users, VFP must pass. But with VFP as front end to a real SQL server you are pretty close to heaven.

With that said, I leave this discussion before Jim Duffy joins it <bg>!

>>>I think its doable. You might have the cleaner solution, but your suggestion that our flexibility tests end after one requirement is entertaining!
