Use of variables in WML is that when CLIENT want to switch over card to card in a deck,than client should have to store the data into variables.

 We can use variables in WML sing two ways:

• Can SET a variable using setvar Command: Suppose that if client want to execute go,prev and refresh type task than they can use setvar command and CREATE a variable with a specific value.

Example:

<setvar name="x" value="9999"/>

• Can set a variable with an input element: If we want to set variable with an input,select, OPTION etc input element.

Example:

<card id="card1">
<select name="enotes">
<option value="PHP">PHP Tutorial</option>
<option value="CSS">CSS Tutorial</option>
<option value="WAP">WAP Tutorial</option>
</select>
</card> 

We can use this created variable enotes into the card2. 

<card id="card2">
<p>You have selected: $(enotes)</p>
</card>

In the above example we create an variable enotes in card1 and passed the selected enotes into card2 by variable enotes.
