J.13. Module ATMCaseStudy

Module ATMCaseStudy (Fig. J.12) simply allows us to start, or “turn on,” the ATM and test the implementation of our ATM system model. Module ATMCaseStudy’s Main method (lines 4–7) does nothing more than instantiate a new ATM object named theATM (line 5) and invoke its Run method (line 6) to start the ATM.

Figure J.12. ATMCaseStudy.vb starts the ATM.
