    Think of a pv! as a "global variable" available across a process model. It can be used to pass values to/from individual smart services and therefore carry values between smart services. You can also use it as an input value to the process model itself (if set as a 'parameter').

    Activity Class variables (ac!) are essentially "private" to individual smart services, and you can pass these values to the smart service implementation  e.g. if a User Input Task then the ac! is the value that is made available to a User Interface via the rule input. You can set the value of an ac! from a pv! and you can save the value of an ac! to a pv!
