title: vbs additional error information
body: <p>Is there any option to get more information about what caused an error in vbs than the the properties <code>err.description</code>, <code>err.source</code>, <code>err.erl</code> and <code>err.number</code>? Helpfile and and HelpContext are not what I'm looking for. More like <code>function 'foo' does not exist</code>.</p>
  
  <p>Those I found on <a href="https://msdn.microsoft.com/en-us/library/ka13cy19(v=vs.90).aspx" rel="nofollow">https://msdn.microsoft.com/en-us/library/ka13cy19(v=vs.90).aspx</a>, but maybe there is an undocumented function or different error handling?</p>
