Hi Juan,

>Would it be better to write a C fll to perform this? My worry is that calling back to VFP (_DBSkip()) would yield the same speed, eventhough I can expect speed increase in other calculations.

Probably not. The _DB functions are almost unchanged since 2.5. They have numerous bugs that don't get fixed and only can work in the default datasession. I haven't tested whether they correctly work with buffering and transactions, but I would at least be careful about such an assumption.

If you have time consuming calculations, put them into a DLL or an ActiveX control (they are faster to call), but leave the data handling in VFP.
