Chapter 19. The WMLBrowser Library
The WMLBrowser standard library provides functions that allow WMLScript code to interact with the browser context.
At some point, there may be a way for something other than WML to
invoke WMLScript functions. (This isn’t the case at the time of
writing, however.) If the WMLScript interpreter isn’t invoked
from a WML browser, each function in this library returns
invalid and has no other effect.
