To reduce a failure time of a computer (1, 4-8) due to a disturbance or interruption in the program sequence, program save points which are time-dependent or can be preset in the main program of a user program are provided and when they are reached, the computer status is stored in at least one failure-resistant archive memory (5, 6). A cascade memory is used as archive memory. <IMAGE> |
