Using the Graphical Simulator10.15.4.2. Interactive ModeGo to Execute Interactively in the script's popup menu. The Interactive Script Controldialog is displayed. Select whether to update the user interface display continuously. Ifcontinuous update is not selected, you can still make the simulator update its display atspecific points in the script by embedding UPDATE records in the script file. You canalso:• Display text strings in the program's status bar by embedding SHOWTEXTcommands in the script.• Cause script execution to temporarily stop by embedding PAUSE commands in thescript.Click the Run button to start executing the script. If a PAUSE record is encountered inthe script, execution temporarily stops and a "Paused" message is displayed in thestatus box. Click Run to continue or Exit to quit.10.15.5. Removing ScriptsTo remove a script from the project, go either to Remove or Remove and Delete in thescript's popup menu. Remove removes the script from the project but does not delete itsfile. Remove and Delete removes the script and also delete its file.10.16. USING SNAPSHOTSSnapshots capture the current state of the simulation session, and can be used torestore the simulation to that state at a later time. Simulation state includes data such asthe current value of application variables, the current state of timer equations, etc.Snapshots might be used if it is necessary to stop a session and pick it back up later.A snapshot becomes invalid once any change is made to any application – logicstatements have been added or deleted, variables have been renamed, etc.To save simulation data in a snapshot file, go to Project | Snapshot | Save in the mainmenu. Enter the file path of the snapshot file and click OK. The current simulation stateis saved, and a numeric “signature” of the project’s applications is calculated and savedas well. The application signature is used to determine whether an application waschanged.To read a snapshot file, go to Project | Snapshot | Read in the main menu. Browse tothe snapshot file and click OK. The application signature in the snapshot file iscompared to the signature for the current applications to verify that no changes havebeen made since the snapshot file was saved. If no application changes have occurred,the simulation session is restored to the state saved in the snapshot file.P2512A, Rev. Oct/09 10–56 Alstom Signaling Inc.
