20.3. The $ Character in WML

WML browsers treat all terms that begin with the $ character as variables. If you want to display the $ character, you should use $$. The following WML example demonstrates this:


<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "http://www.wapforum.org/DTD/wml13.dtd">

  <card id="cell_phone_card" title="Buy Cell Phone">
      The price of the cell phone in your shopping cart is $$200. Do you want to proceed to checkout now?<br/><br/>

      <a href="#checkout.wml">Yes. Proceed to checkout</a><br/>
      <a href="#product.wml">No. Continue shopping</a>

The following screenshots show the result of the above WML example in some mobile phone browsers:
