The <go> tag has a central role in WML. The user agent can change cards by the tag. This tag can call either a WMLScript function or move to another card of the WML deck. In the following example, clicking the Help option triggers a switch to card card1_help:

<do type="help" label="Help">
  <go href="#card1_help"/>
</do>

Clicking the Calculate option in the following example, triggers a call to a WMLScript function called convert, defined in the WMLScript currency.wmls:

<do type="accept" label="Calculate">
  <go href="currency.wmls#convert('conversion','$(from)',
                                       '$(to)',$(amount))"/>
</do>
