+
+This quick start demonstrates how to implement a SAS program on
+HCC supercomputers through the command line and JupyterHub, and on HCC's Anvil platform. The sample code and submit scripts can be
+downloaded from [HCC's job-examples git repository](https://github.com/unlhcc/job-examples).
+
+## SAS on HCC Clusters
+SAS applications can be ran on HCC clusters similar to other jobs.
+[Connect to a HCC cluster]({{< relref "../../connecting/" >}}) and make a subdirectory
+called `sas_demo` under your `$WORK` directory.
+
+In the subdirectory `sas_demo`, save the sas code. Here we include a single demo
+programs, `t_test.sas`, to perform a t test analysis on a small data set.
+
+{{%expand "t-test.sas" %}}
+{{< highlight sas >}}

+
+#### Creating a Submit Script
+
+Create a submit script to request one core (default) and 10-min run time
+on the supercomputer. The name of the main program enters at the last
+line.
+
+{{% panel header="`sas.submit`"%}}
+{{< highlight bash >}}
+#!/bin/bash
+#SBATCH --nodes=1
+#SBATCH --ntasks-per-node=1
+#SBATCH --mem=1gb
+#SBATCH --time=00:10:00
+#SBATCH --job-name=sas_example
+#SBATCH --error=sas_example.%J.err
+#SBATCH --output=sas_example.%J.out
+
+module load sas/9.4
+
+sas t-test.sas
+{{< /highlight >}}
+{{% /panel %}}
+
+#### Submit the Job
+
+The job can be submitted through the command `sbatch`. The job status
+can be monitored by entering `squeue` with the `-u` option.
+
+{{< highlight bash >}}
+$ sbatch sas.submit
+$ squeue -u <username>
+{{< /highlight >}}
+
+Replace `<username>` with your HCC username.
+
+#### Sample Output
+
+The results of the t-test are computed and printed to the `.lst` file (see
+below).
