title: What does the symbol :=: mean (colon equals colon)
body: <p>I've found the symbol <code>:=:</code> in some Clarion code and I can't seem to figure out exactly what it does.  The code was written by a previous developer many years ago, so I can't ask him.  I also have not been able to find any results for <code>"colon equals colon"</code> in Google.</p>
  
  <p>Here is an example of the code, where <code>bufSlcdpaDtl</code> is a file object:</p>
  
  <pre><code>lCCRecord Like(bufSlcdpaDtl),Pre(lCCRecord)
  
  ! ...other stuff...
  
  lCCRecord :=: bufSlcdpaDtl
  </code></pre>
  
  <p>I'm wondering if it's something similar to <a href="https://stackoverflow.com/questions/9196066/what-does-a-double-colon-followed-by-an-equals-sign-mean-in-programming-do"><code>::=</code> in Python</a> or possibly <a href="https://stackoverflow.com/questions/5344694/what-does-do">the assignment operator <code>:=</code></a>.</p>
