title: What is the point of BLOCK in Fortran?
body: <p>I am looking at some code and there is this:</p>
  
  <pre><code>BLOCK
  
  ...lines of code...
  
  END BLOCK
  </code></pre>
  
  <p>What is the purpose of <code>BLOCK</code>? I tried to google it, but all I found was something about <code>BLOCK DATA</code> and <code>COMMON</code> blocks. I'm not sure whether they are related.</p>
