NO-ERROR
If an error occurs on the statement with NO-ERROR, the AVM undoes the action of the statement and continues execution with the next statement rather than raising ERROR. In addition, all error messages are diverted to the ERROR-STATUS system handle rather than being displayed to the current output device. The information stored in the ERROR-STATUS system handle remains until the next statement using NO-ERROR. To check for errors after a statement that uses the NO-ERROR option:
  • Check the ERROR-STATUS:ERROR attribute to see if an error was encountered during the execution of the statement. Note however that sometimes errors are treated as warnings and ERROR-STATUS:ERROR is not set.
  • Alternatively, check if the ERROR-STATUS:NUM-MESSAGES attribute is greater than zero to see if the AVM generated error or warning messages.
  • Use ERROR-STATUS:GET-MESSAGE( message-num ) to retrieve a particular message, where message-num is 1 for the first message.

NO-ERROR has no effect when a STOP or QUIT condition occurs.

If an error object is thrown to a statement that includes the NO-ERROR option, the information and messages in the error object are used to set the ERROR-STATUS system handle.

For more information on using NO-ERROR and error handling in general, see ABL Error Handling.
