My new programs works with codepage 1250 (Czech Windows Page), but I share some data with old programs, that my customers use sucessfuly for several years and nobody want to change them now. That is why I need to select data from DBF files with different code pages in one program (1250,852).
I have tried the command SET ENGINEBEHAVIOR 80 at first, but the Rushmore optmization level was NONE in any case after recompilation by VFP9.
