An Internet is connected to both a host computer and a computer numerical controller that is controlling a CNC machine. Stored therein the controller is an encrypted program which requires a pre-paid license to decrypt the encrypted program first before execution of the program by the controller is made possible. When the number of pre-paid licenses are all used, the controller facilitates the purchase of a number of pre-paid licenses with the host computer via the Internet.
