Depending upon how the application is constructed, you can also pass values back and forth between processes if the processes have a parent-child relationship. Thus a parent will pass value to a child when it is created, and the final value will be passed back when the child is completed. In this way parent and child processes can share variables -- but of course in this case the value at run-time is not truly shared ... it is passed back and forth.
