The operation is performed on the list of events, which must be loaded beforehand. Automatic processing of the event list is invoked from the menu with the Process events 
Process step by step command. This operation consists in processing all events from the loaded list in turn, starting from the first one. After processing one event, the program proceeds to the processing of the next one, until the list is finished or the process is interrupted from the menu with the command Process events Stop the step by step processs. Processing is carried out according to the menu commands stored in the file ProcessStepByStep.bat.
Where interpretation requires operator interaction, as with most GUI functions, the event list auto-processing cannot be used and must be processed separately (see One event selection and processing).
