title: Print multiple variables with one command in GDB
body: <p>I want to execute the very simple command</p>
  
  <pre><code>print var1, var2, var3, var4 
  </code></pre>
  
  <p>in gdb to examine the values of the vars from time to time.</p>
  
  <p>I don't want to use display because it clutters up my view.</p>
  
  <p><em>How can I do this?</em> Right now all I can do is:</p>
  
  <pre><code>p var1  
  p var2  
  p var3  
  p var4  
  </code></pre>
