Using the editors in test mode

In Test (On Line or Simulation) mode, all editors are animated with real time values of the edited objects:

When you double click on a variable symbol during debug, a dialog box is open and enables you to change the value of the variable. It also enables you to "Lock" or "Unlocked" variable. When a variable is locked, its value is no more changed by the runtime. You can then force its value from the debugger independently from the runtime operations. Note that the set of variables that accept to be locked depends on the build options.
