     // You need to quote ASCII with [] to make sure it is not read as a reserved U-SQL keyword
     @Trips =
         EXTRACT date    DateTime,
             driver_id   int,
             vehicle_id  int,
             trips       string // Array
          FROM "/Samples/Data/AmbulanceData/DriverShiftTrips.csv"
          USING Extractors.Csv(encoding: Encoding.[ASCII]);
     OUTPUT @Trips 
     TO "/Output/ReferenceGuide/BuiltIn/UDOs/extractorCsv_DriverShiftTrips.csv" 
     USING Outputters.Csv();
