Abstract

PURPOSE:To update a program without interrupting a system even in online repairing, by checking whether program update is enabled or not by a control-number counter. CONSTITUTION:A control table 13 in which programs controlled by a system and address information on the programs are registered is provided, and while a logical storage space 12 is divided into several fixed areas, control-number counters 3 are provided corresponding to the areas. When execution control over a computer is transferred from some area to another area by an instruction other than an instruction which updates directly a program status word holding the address of an instruction to be executed, the control-number counter 3 corresponding to the area is permitted to goes up by one. When it is transferred from an area which is not interrupted to another area, the counter goes down by one. To discriminate whether during system operation is enabled or not, if the control-number 3 for a logical storage space 12 occupied by the program of an object to be updated shows a 0, up- date is feasible.
