Please add alert for this bug

[dle]

The following command errors don't get alert

Private String OpenFile = File.Open(report_location, 0, 1, 1, 1)
File.Write(OpenFile, "," + DoubleToStr(testing_sequence[1]) + "," + testing_date_time[1] + "," +
                                 testing_technician[1])

There suppose to be a "\" next to the "+" at the end of line 2. In the past, this error will get alert but current version 16.3 won't.

Thanks.
