Create a missing routine implementation
    When you create a routine, it contains the forward declaration and the implementation.
            The forward declaration contains the 
extern
 keyword, such as
                extern routine myRoutine()[];
. If the forward declaration is specified but the implementation does not exist, you
            receive the error
