After selecting 'Run' the current program is started and processed. If the program ends with 'RPT', the program is repeated continually. 'Esc' interrupts the running of the program after concluding the cycle just in progress. 'End' immediately interrupts the program after completing the command in the current line. For each stop that has been set, the pro- cessing of the program line, in which the stop was set, is concluded. Subsequently, the program stops and can be continued again by pressing any key.
