Pass a numeric value from VFP - the COM interface code within VFP takes care of the conversion.

You don't have named parameters, so theymust be passed explicitly in the proper order; you can normally just put sequences of commas omitting optional parameters. Don't forget to pass by reference where you expect to receive a return value via a parameter. If an array is coming back, you'll probably need to use the COMARRAY() function in VFP for formatting the array properly.
