Jim,

Ok, fourth times the same story :) I said, that I'm using editbox for this input. For Piter sake, don't convince me to switch into textbox+listbox+2 buttons or grid+2buttons. And I still need to place something in the valid method. So, why my 'valid' method is harder, that nobody can accept it? I understand, that since we have not InputMask for editbox, it's worth to verify user's input. As I wrote, it would be nice to have this feature in Editbox and I already wrote about it in VFP7.0 wish list. Same story about Pages visibility.
Anyway, my code works and code itself is simple. I assume, that there would be no more than 5-6 lines, so this code executes in seconds.

Yes, interesting approach. I promise, that next time I will use it. Ok?
If it's not broken, fix it until it is.
