Exit Values
When a program terminates and returns to the WXP shell or operating system shell, it will return a value resolvable by the shell called an exit value that can resolve whether the program ran successfully or not. If an error occurred, the exit value will explain, to a certain degree, the type of error so that a shell script can handle the error and perform any error recovery. The following is a list of possible exit values.
