title: how to pass blank to batch file as parameter
body: <p>I need to pass blank("" or " ") to a batch file as parameter.  </p>
  
  <p>I have to pass the runtime values to a url. My url is: </p>
  
  <pre><code>start iexplore http://example.com?emailAddress=%1&amp;name=%2&amp;phone=%3&amp;dateofbirth=%4&amp;hobby=%5&amp;address=%6
  </code></pre>
  
  <p>Everything works fine if all parameters have some value, but if the value of any of the parameters is "" or " ", i.e., blank, the next non-blank value is assignment and the sequence is disordered.  </p>
  
  <p>Please help !</p>
