title: SAS: Data Step and additional row
body: <p>i have an data step. </p>
  
  <pre><code>   data One;
        set Two;
        /*some code*/
     run;
  </code></pre>
  
  <p>How to add additional row after last row of new table? </p>
  
  <p>Is it possible to do optimal? (<code>One</code> table may have many rows ~ 100k - 10M)</p>
  
  <p>Thanks!  ( it is <code>TOTAL</code> row, yes )</p>
