2.5 Selecting a SAS task

To get a list of all the SAS tasks, start the main SAS GUI by typing the command sas on the command line. A particular SAS task GUI can simply be invoked by double-clicking on its name on the provided list. The use of the SAS GUI is explained in § 3. The SAS tasks can be grouped by:

A list of packages in alphabetical order or classified by group is available at:

http://xmm.esac.esa.int/sas/current/doc/

For detailed descriptions of individual tasks, the user is referred to the SAS package descriptions which can be accessed at the above address or via the SAS GUI help button. As a starting point, the user can read the package documentation of the list of frequently used tasks provided in Table 1.
