GetDynamicField

The GetDynamicField() method must be defined with a single argument, expected to be a string.When a field reference is performed for an object that is not in the class definition, the GetDynamicField method is automatically invoked if it has been defined. The name of the field which could not be found will be passed to the function as its only argument. The function would use this argument to determine an appropriate value and return that value using the RETURN statement.
