public final class Assign
extends VoiceXmlNode

The <assign> element assigns a value to a variable:

<assign name="flavor" expr="'chocolate'"/>
<assign name="document.mycost" expr="document.mycost+14"/>

It is illegal to make an assignment to a variable that has not been explicitly declared using a <var> element or a var statement within a <script>.
