# Running SAS Interactively

On the Yens, SAS is available via the `module` command.

See all currently installed versions with:

Terminal Input

```
module avail sas
```

You will see the current SAS versions listed:

Terminal Output

```
-------------------------------------------- Global Aliases --------------------------------------------


---------------------------------------- /software/modules/Core ----------------------------------------
   sas/9.4
```

## Load SAS Module

To use SAS software on the Yens, load the module:

Terminal Input

```
ml sas
```

This will load the default SAS module. You can also load a specific version of SAS with:

Terminal Input

```
ml sas/9.4
```

## Running SAS Code

To execute a SAS script at the terminal, run:

Terminal Input

```
sas <your-script.sas>
```

where `<your-script.sas>` is your SAS script.

Note that SAS output is provided in a log file called `<your-script.log>`.

Graphical SAS

SAS can be also be accessed in a graphical form using [Jupyter Notebooks](/_getting_started/jupyter/#sas) or [X-Forwarding](/_user_guide/using_gui).

## Other SAS Environments

Depending on your needs, you may prefer using SAS in a different environment.

- [SAS Studio on WRDS](https://wrds-www.wharton.upenn.edu/pages/grid-items/using-sas-studio/) provides a web-native graphical interface with access to the GSB's licensed data on WRDS.
- Your machine may be a more effective place to develop your code, given the native GUI. There is a [free license](https://uit.stanford.edu/service/softwarelic/sas) for SAS at the University level.
