Thanks for the help Craig, but I was wondering why the VB line:

Set oSvc = New AddressSvc

Is converted to:

oSvc = New AddressSvc

Which obviously does not compile in VFP. If I change it to:

oSvc = "New AddressSvc"

It destroys the object created with:

oSvc = CreateObject("Avalara.AvaTax.Adapter.AddressService.AddressSvc")
