## \<script> <a href="#script" id="script"></a>

The `<script>` element allows the specification of a block of client-side scripting language code, and is analogous to the HTML \<SCRIPT> element.

### Notes

It is advisable to place all script text between CDATA delimiters: “\<!\[CDATA\[” and “]]>”. Alternatively, conditional ECMAScript expressions that use the “<” or “>” symbols can use the replacements “\&lt” and “\&gt”, respectively.

### Example

```markup
<?xml version="1.0"?>
<vxml version="2.0">
  <form>
    <script>
      test_var=1234;
    </script>
    <block>
      <prompt>
        The test variable is set to <value expr="test_var"/>.
      </prompt>
    </block>
  </form>
</vxml>
```

The output of the above script would be:

> Computer: The test variable is set to twelve hundred thirty-four.
