Hi Boris 
    Thanks for quick response. I'm using spidermonkey 45. can I rename the global object as in v8. I have tried 
                   run(cx, e.dialog, "globalThis.x"); 
but still same output. 
noname:1:ReferenceError: globalThis is not defined 

please consider that I'm new to spidermonkey so parden me if I'm missing something obvious. 

My main goal is to achieve scoping in vxml interpreter which allow users to run scripts as follow 

<?xml version="1.0" encoding="UTF-8"?> 
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  xsi:schemaLocation="http://www.w3.org/2001/vxml 
   http://www.w3.org/TR/voicexml20/vxml.xsd"> 
  <form> 
    <script> 
      var now = new Date(); <!-- this has a dialog scope--> 
    </script> 
    <var name="seconds" expr="now.getSeconds()"/> <!--this has a dialog scope-> 
    <block> 
      <var name="now" expr="new Date()"/><!--this has an anonymous scope --> 
      <script> 
        var current = now.getSeconds();   <!-- "now" in the anonymous scope --> 
        var approx = dialog.now.getSeconds();<!-- "now" in the dialog scope --> 
      </script> 
    </block> 
  </form> 
</vxml>
