If you have modified examples and want to reinstall the original clean version, delete the examples directory and restart Sybase CEP Studio. The original examples are automatically recreated.
Note that, even if you uninstall and reinstall Sybase CEP, your examples directory survives if you have made any changes to it. To get fresh examples, you must delete the examples directory. When you install a new version of Sybase CEP Engine, it will install a new set of examples into a new examples directory under the new version number.
