title: Treat missing values as zero in SAS where clause
body: <p>Is there an equivalent of the Oracle NVL function in SAS?</p>
  
  <p>For example, if I have a where clause in SAS that says:</p>
  
  <pre><code>where myVar &gt; -2;
  </code></pre>
  
  <p>it is not going to include any rows that have myVar = .</p>
  
  <p>If I want to treat missing values as zero, i have to say:</p>
  
  <pre><code>where myVar &gt; -2 or missing( myVar )
  </code></pre>
  
  <p>I'd like to be able to do something like:</p>
  
  <pre><code>where NVL( myVar, 0 ) &gt; -2 // or some SAS equivalent
  </code></pre>
  
  <p>Is there something like this in SAS?</p>
