Info

After pressing that button, the following wizard pops up: You can then enter the events you want. As indicated, the following elements can be entered: name, parameters, guards, and actions. More parameters, guards and actions can be entered by pressing the corresponding buttons. If more events are needed then press ”Add”. Press ”OK” when you’re finished. Note that an event with no guard is considered to have a true guard. Moreover, an event with no action is considered to have the ”skip” action. 3.5.2 Direct Editing of Events. It is also possible to perform a direct creation (button ”Add Event”) of variables by using the central editing window. For this, you have first to select the ”Events” tab of the editor. You can also change the relative place of a variable: first select it and then press button ”Up” or ”Down”. 22
Once an event is selected you can add parameters, guards, and actions. The components of an events can be seen by pressing the little triangle situated on the left of the event name: As can be seen, event rmv 1 is made of two parameters, x and y, three guards, x ∈ Q, y ∈ Q, and x ↦→ y ∈ k, and one action Q := Q \ {x}. These elements can be modified (select and edit) or removed (select, right click on the mouse, and press ”Delete”). Similar elements can be added by pressing the relevant buttons on the right of the window. 23
