At the start of a SAS session, one normally selects the ODF to be processed, setting the environment variable SAS_ODF pointing either to the directory containing the ODF files, or to the ODF Summary File (as explained under 2.3). Choosing `Preferences' from the `File' menu pops up a dialog into which the path of another ODF directory (or ODF Summary File) can be entered.
The ODF directory can be specified either by an absolute path (starting with `/') or as a path relative to the directory in which the SAS GUI was started. The `..' button pops up a dataset browser which allows to search for the directory and select it.
It is possible to select a different ODF directory at any time during the session. Any tasks run subsequently will use the new ODF.
