	External subroutines are the same as external functions except that they return a value.
	Local external functions must be declared before using it in script.
	Global external functions do not need to be declared before using them in script.
	Local external functions are part of the object’s definition and can always be used in scripts for the object itself.

	You can call Global functions using the DYNAMIC keyword.
Question: 217	Identify the CORRECT statements with regard to the AncestorReturnValue variable? (Choose 2)
Answer	The AncestorReturnValue variable is generated if you extend the ancestor script and use the CALL syntax to call the ancestor event script.
	When you extend an event, the compiler automatically generates a local variable called AncestorReturnValue.
	When you extend an event, the compiler automatically generates an instance variable called AncestorReturnValue.
	The AncestorReturnValue variable is generated if you override the ancestor script and use the CALL syntax to call the ancestor event script.

	n_utility’s methods and properties may be accessed directly through the class.
	The statement “gnv_utility = CREATE n_utility” may be used to reinitialize the instance.
	If n_utility declares an instance variable of class n_utility, the object will not save.
	n_utility represents an appropriate use of the AutoInstantiate property.
