Use SAS on Karst at IU

At Indiana University, SAS is available on the Karst research supercomputer. You can run SAS interactively, non-interactively, or as a background process.

Add SAS to your user environment

To add SAS to your user environment, load the SAS module:

  module load sas

To make permanent changes to your environment, edit your ~/.modules file. For more, see Use a .modules file in your home directory to save your user environment on an IU research supercomputer.

Run SAS interactively

To run SAS interactively, on the command line, enter:

  sas -nodms

When SAS initializes, the SAS command prompt (1?) will display. The number appearing with the question mark in the prompt will increase with each subsequent command line. Enter your command(s) and terminate each SAS command with ; (semicolon). For example, to execute a statement, enter:


To end the session, at the SAS prompt, enter:


Run SAS in non-interactive mode

To run a SAS job non-interactively, on the command line, enter:


Replace with your SAS program's filename. When the job has been executed, two new files will exist in your default directory. The SAS log, program.log, will contain the code that was run along with any notes, warnings, or errors that resulted during execution. The listing report, program.lst, will contain output from the program, if any. In both cases, program represents the name of your SAS program file. If your program file contains errors, the .lst file may not be generated.

Run SAS as a background process

When you run a non-interactive job, your terminal is not free for other computing tasks until the job is completed. If you want to use your terminal for computing activities while the job runs in the background, include & (ampersand) at the end of the command:

  sas &

Again, replace program with the name of your SAS program.

This will free your terminal for other computing tasks while the job runs in the background. When the job is completed, a message will be displayed on the screen, and the .log and the .lst files will be stored in the default directory.
