If a line being translated contains an error, the error column and length members of the RPN list were set to the error. Previously the translator also set the error message member to the error message. Continuing with the change from error messages to error status codes, this error message was changed to an error status code. The translator was modified to set the error status instead of the error message. The receivers of an RPN list, the program model and tester classes, were modified to take the error status code from the RPN list and get the error message for the status code.
