ABSTRACT:
In the processing of instructions in data processing systems it is not always possible to execute these instructions without interruption since particular situations, in the following called events can occur which necessitate a short interruption for executing the operations caused by such events before continuing the interrupted instruction processing. Such repetition however is only possible when the contents of the operation register containing the instruction is frozen during the interruption. Such a situation requires two actions: the first is the execution of a forced operation to resolve the event. The second action is a repetition of the instruction and execution phase of the interrupted instruction.
