Thanks Sergey. That's what I did. I thought there could be another way. As for the other I probably have them all. I mean logical, strings, numeric. And I hope to be able to make that move to VFP9 soon. I already tested some things in my app in VFP9 and it looks ok.

Is it possible to add memo? This one is just out of curiosity. Not that I need it and I guess that string could be used instead.
