This section describes how to add a constant to your module and configure it.
Add a constant to the module of your choice. If you do not know how to add documents to a project, please refer to this article.
Enter a name for the new constant.
In the new menu, you can optionally add documentation describing the constant, choose its type, and choose its values, depending on the configuration.
For example you might want a constant which contains the location of a Web Service, having different values depending on whether the application is run in a development or test configuration.
