3.6 Adding Comments It is possible to add comments to variables, invariants, theorems, events, guards, and actions. For doing so, select the corresponding modeling element and enter the ”Properties” window as indicated below where it is shown how one can add comments on a certain guard: Multiline comments can be added in the editing area labeled ”Comments”. 3.7 Pretty Print The pretty print of a machine looks like an input file. It is produced as an output of the editing process: 24
3.8 Dependencies: Refining a Machine A machine can be refined by other ones. This can be done directly by selecting the machine to be refined in the ”Project Explorer” window. A right click on the mouse yields the following contextual menu: You then press button ”Refine”. A wizard will ask you to enter the name of the refined machine. The abstract machine is entirely copied in the refined machine: this is very convenient as, quite often, the refined machine has lots of elements in common with its abstraction. 3.9 Adding more Dependencies 3.9.1 Abstract Event The absraction of an event is denoted by a ”Refine Event” element. Most of the time the concrete and abstract events bear the same name. But, it is always possible to change the name of a concrete event or the name of its abstraction. If you want to specify the abstraction of an event, first select the ”Event” tab of the editor and right click on the event name. The following contextual menu will pop up: 25
