Hi,
Ya, That why I use that formula to check the tablevalidate in VFP6.
However, now I found that the result of formula may not same with ADIR/FIZE()
Therefore, it is impossible for me to use that formula to check data loss.
I am not the most powerful man in this world.
I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
