title: In q, how to add a symbol to a symbol
body: <p>I'm trying to <code>load</code> a table with a variable name.</p>
  
  <p>Let's say:</p>
  
  <pre><code>a:`partofurl;
  </code></pre>
  
  <p>Then this doesn't work:</p>
  
  <pre><code>load `:c:/q/a/table;
  </code></pre>
  
  <p>So how can I use the variable <code>a</code> in the url <code>symbol</code> expression?</p>
