2.1.3 Global Settings

The following table lists global constants which are defined at compile time and can not be modified by the user. Where the user would want to use different values, some other well-defined mechanism usually exists (for instance, use command line options or environment variable to specify new values for the INPUT_FILE variable).

These values are used most often in error checking, and are referred to both in 2.4 Error Messages and in the descriptions of individual commands.
