Hi Aleksey,
i'm not been born with English,
but what you write and what writes the documentation they seem in contradiction.

1. You can explain why they are not in contradiction?

>from the table without additional code page translation even when
>current code page (CPCURRENT()) does not match code page tagged to the table (CPDBF())
>in order to produce the same index regardless of the current code page.


2. If VFP don't traslate the data table, why it cannot use the index ?

3. for a (binary) field ( NOCPTRANS ) this limitation does not happen?

Thanks
Fabio
