Hi Gregory,

>What can I say ?

Only that Round() have a bug.

Thanks for the API reference.

Then, for sure computations, i need implement all VFP computations on a FLL module ?
No thanks, if this is the only way, i go directly to a free C++
( no .NET, because with managed code i put basic elements on other hands ).

Now i survive because all computations are done on SQL backend, but on future ....
