Hi
If the AS400 can consume Web Services, that's the way to go. If not, check if they can browse to an ASP page. If yes, just create an ASP page in the machine where your VFP app resides( visible from the AS400, of course ), and have the ASP page CreateObject( YourVFPCOMObject ). From the AS400, POST the data to the ASP page, and GET the resulting string.
