Syntax Description


limits access to the Sasuser data library to Read-Only access in environments where all users share the Sasuser library.


enables a user to open a file in the Sasuser library for Update access, thus preventing users from sharing members of the Sasuser data library. Update access to the Sasuser library requires exclusive rights to the data library member. NORSASUSER is the default value.


Specifying RSASUSER enables a group of users to share Sasuser data library members by enabling all users to have Read-Only access to members. For example, if RSASUSER is in effect, each user can open the Sasuser.Profile catalog for Read-Only access, enabling other users to concurrently read from the Profile catalog. However, no user can write information out to the Profile catalog; you receive an error message if you try to do so.
Specifying RSASUSER in a SAS session affects only that session's access to files. To enable a group of users to share members in the Sasuser data library, the system administrator should set RSASUSER in the network version of the SAS configuration file, which is shared by all users who share the Sasuser data library.
If you specify RSASUSER but no Profile catalog exists in the Sasuser data library, the Profile catalog is created in the Work data library.
Whether the RSASUSER system option is useful depends on how SAS is being used. The RSASUSER system option is extremely useful when users must share information (such as the Profile catalog) stored in the Sasuser data library. RSASUSER is not useful if these same users are using SAS/ASSIST software. SAS/ASSIST software requires Update access to the Sasuser data library.
