PURPOSE:To eliminate such a defect that processing needs to be interrupted since malfunction is caused when a destroyed area is accessed if the memory area stored with a program is destroyed during operation. CONSTITUTION:The program A which is loaded in the destroyed part 12 is reloaded in another free area A and information on the disk descriptor 11 regarding the destroyed part 12 is moved to a substitute descriptor area 113. Substitution destination information and a substitution completion code 110 are registered in an original descriptor area 11. Consequently, even if the destroyed area is accessed, substitute access to a program reloading area is performed according to the substitution completion code and substitution destination information, so the processing is not interrupted. |
