You're right !
the table codepage isn't the same as Windows.

>>And for the problem of ENGINEBEHAVIOR, I have made some tests. If I create a table under VFP9 with an index, I have a "full" Rushmore optimization level (with SET ENGINEBEHAVIOR 90). The same table created with a prior version of VFP gives me a "none" Rushmore optimization level. I have to set ENGINEBEHAVIOR to 80.
