Your application typically uses the default set of global constant values defined in the application. You can set up alternate values for the global constants. For example, you can define and use constants for all strings you use in an application. You can create one set for each language you want to use.

The default set of constant values is stored in the database. You can create alternate sets of constant values and store them in files. You can override the default constants by specifying the file name before running an application or creating an image of an application.

When a global constant file is specified before running the application or creating an image, the values in the constant file override the default values stored in the database. The values in the constants file are in effect until you clear the field, specify a different filename, or edit a different application.
