You cannot pass a VFP array to a dll function.

You must use the DECLARE-DLL command to declare the dll function(s) and here are the equivalences:

        VFP (in DECLARE) VFP (normal)
        ---------------- ------------
double: DOUBLE           Numeric
long:   INTEGER          Numeric
byte:   STRING           String

You have to simulate the arrays with using strings. Strings must be passed by reference.
