Declaring a WMLScript External Function

To make a WMLScript function accessible to a WML file, you must include the extern directive in the function declaration. The external function must also include at least one variable or parameter if the WML and WMLScript are to interact in complex and interesting ways.

For example:

extern function myfunction(cardURL)

var state;

var action;

var image;

... //function implementation
