B.2 Configuration techniques

There are many ways that PSPP can be configured. These are described in the list below. Values given by earlier items take precedence over those given by later items.

1. Syntax commands that modify settings, such as SET. See SET.
2. Command-line options. See Invocation.
3. PSPP-specific environment variable contents. See Environment variables.
4. General environment variable contents. See Environment variables.
5. Configuration file contents. See Configuration files.
6. Fallback defaults.

Some of the above may not apply to a particular setting. For instance, the current pager (such as more, most, or less) cannot be determined by configuration file contents because there is no appropriate configuration file.
