title: Regex to match word, followed by zero or more digits?
body: <p>I need a regular expression to match line beginning with a specific <code>WORD</code>, followed by zero or more digits, then nothing more. So far I've tried this:</p>
  
  <pre><code>^WORD\d{0,}
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>^WORD[0-9]*
  </code></pre>
  
  <p>But it doesn't work as expected: it is also matching lines like <code>WORD11a</code>, which I don't want.</p>
