title: Replacing value in SAS
body: <p>I have some variables having values <code>-980, -987, -995</code>.</p>
  <p>Dataset</p>
  <pre><code>fact_1   fact_2   fact_3   fact_4 
   0        -980     -21      -995    
   12         0      -987     -214   
   24        12      43       -124   
  ...
  </code></pre>
  <p>I would like to replace with a missing value where var has values listed above: <code>-980, -987, -995</code>.</p>
  <p>Expected output:</p>
  <pre><code>fact_1   fact_2   fact_3   fact_4 
   0          .    -21         .      
   12         0      .        -214    
   24        12      43       -124   
  ...
  </code></pre>
  <p>Can you please tell me how to do it in SAS? I would use replace in Python but I actually I do not know how to check if a variable has a specified value to change in SAS.</p>
