A value will be assigned to 'cdata', but it will happen within the frame of
the callback. You'll need to do something with it there, or use the <<-
operator to assign it to the global workspace (recommended only while you
prototype). In the context of a larger application, you'll need an
underlying mutable data model, perhaps implemented with a reference class
object or an environment.
