Value assignment

The <h2> element is used to assign a new value to an existing variable, specified by the id. For example:

<h2 id="foo">
    <b id="+">
        <p id="10"></p>
        <p id="foo"></p>
    </b>
</h2>

is compiled as

foo = 10 + foo

Please note that foo must be previously declared with <h1> element. If foo is not previously declared, the compiler won't give you an error, but the JS code will not work.
