BASIC returns run-time error messages if an error occurs while a program is executing. BASIC diagnoses the error and indicates the program line that generated the error. Warning error messages indicate that an error has occurred, but program execution continues. In some cases, VAX BASIC re-prompts for more information or correct data. In other cases, BASIC performs the specified operation, but the results are not as expected. Fatal error messages indicate that the program has aborted. You can recover from most fatal errors by including error-handling routines in your program. Certain errors, however, are not recoverable even when error-handlers are used. In the description of these errors, they are designated as not trappable. You do not need error-handling routines to trap errors that generate warning messages.
