# Exit Code Mappings

For particular runtime environments ReCodEx can provide mappings of result codes to some custom messages. This is possible for example for Java, C# or Python where there can be custom wrappers/runners which might catch exceptions and then provide users more detailed information about evaluations.

## Free Pascal

Actually, the FPC itself returns a specific code when a runtime error is encountered. All exit codes on the runtime errors list are translated into corresponding strings according to FPC documentation: [https://www.freepascal.org/docs-html/user/userap4.html](https://www.freepascal.org/docs-html/user/userap4.html)
