Message        The last statement in non-void function "<name>" is
                not a return statement.

 Description    A function that returns a value does not end with a
                return statement.  If function execution reaches the
                end of the function, the implied return statement
                that executes will return an undefined value.  This
                might not have been what you intended.

 User Action    End the function with a return statement that
                specifies a return value.
