Okay - I'm trying out the encoding like you suggested. The programmer that wrote the webservice is looking for the data to come in one big string like this:
 rc = http_url_get_xml('http://10.223.30.230/'+             
                        'RTITripWS/TripService.asmx/'+      
                        'GetTripUtilization?'+              
                        'OrderNumber=' + %trimr(OrderNo) +  
                        '&SequenceNumber=01' +              
                        '&PTA= 12252004' +                  
                        '&Status=WHAT' +                    
                        '&UnitNumber=  3302' +              
                        '&DrvLstCtySt=MARSWI' +             
                        '&DrvLstLat=0' +           

When I encode, do I include the '&' in front of the fields?  The programmer said that's what tells him it's a new field.  Basically he's looking for a '?' in front of the first field, and an '&' in fron of all of the others.
