Setting Up SAS Files

Using SAS/ASSIST Software to Assign a New Libref

SAS automatically assigns the libref SASUSER to a SAS data library under your operating environment so that you can permanently store your work without assigning another libref.

To assign a new libref, follow this selection path: Tasks Setup File Management SAS data librariesThe SAS Data Libraries window appears.

SAS Data Libraries Window

Note that under z/OS, there is an additional option for Table information. This option provides information about the operating environment and a list of allocated DDNames.
Select List current librefs. The Select a Library window appears with a list of the currently assigned librefs. The purpose of this step is just to view the current list of librefs.

Library Selector Window

Note: The preceding display shows the Select a Library window for the UNIX operating environment. Other operating environments may have different formats for the Host Path Name.
Select Cancel to return to the SAS Data Libraries window.
Select Assign a new libref from the SAS Data Libraries window. The Assign a New Libref window appears.

Assign a New Libref Window

Note: Under z/OS, the Host Options button in the Assign a New Libref window is used to specify operating environment-specific parameters such as disposition and space.
In the Libref field, type the libref you want to use. Follow the naming conventions described previously. For this example, type MYDATA .

In the Name of the SAS data library field, type the name you want to use according to the naming conventions described below.
- Under z/OS, type a fully qualified operating environment table name, for example, USERID.SAS.DATA.
- Under UNIX, type the name of an existing directory or subdirectory, for example, MYDATA.
- Under Windows, type the name of an existing directory or subdirectory, for example, C:\SASDATA.
- Under OpenVMS, type the name of an existing directory or subdirectory, for example, [MYDATA].
Select OK. A message appears that indicates that the libref was successfully assigned. Select Goback.
Under z/OS only, if the file is not allocated, the software will prompt you to allocate the file and then allocate it for you. The SAS Data Libraries window reappears.
Select List current librefs again. This time the libref you just assigned is listed.
