title: How do I change the label in a data step header?
body: <p>In SAS you can do.</p>
  
  <pre><code>data a(rename=(a=b) );
    a = 1;
  run;
  </code></pre>
  
  <p>to rename a variable in the data step data statement (or data step header as I call it).</p>
  
  <p>What's the syntax to change the label? I tried </p>
  
  <pre><code>data a(label=(a='a to b') );
    a = 1;
  run;
  </code></pre>
  
  <p>But it doesn't work. </p>
