APPENDIX A ERROR MESSAGES When an error occurs, one of the error messages listed below will be displayed. For errors which occur during program execution, the error message is followed by the line number in which the error occurred. The error number and the line number are stored into the variables ERN and ERL, respectively. Errors which occur during direct input operation do not change the values of the variables ERN and ERL.
