The default behaviour of Invantive Script is to end the execution of a script when an error occurs and to continue when no error occurs. Using the on error statement with the syntax: ``` local on error SPECIFICATION ``` you can control the behavior when an error occurs. The available variants for specification are: - `default`: as described above. - `continue`: remember that an error occurred, continue execution but exit the program with the exit code that would have been raised during default behavior. - `ignore`: ignore the error and forget it ever occurred. - `exit success`: exit the program with exit code 0. - `exit failure`: exit the program with exit code 1. - `exit warning`: exit the program with exit code 2.
