Build a VB class with eposing properties for each parameter.
Give it an execute function copying all the properties into VB variables,
make the working call, copy all the interesting Ref vars back into properites.

Instantiate this VB COM object in vfp,
set the properties,
call the method,
read out any interesting data....

Most of the time fast enough if not called in tight loops,
even if bloody chatty across COM barriers, but you can work on and
try a faster solution when it becomes necessary.
