PURPOSE:To reduce the number of processes to be executed by a program controller and to easily control also an old program by partially entrusting the control of a directory to be referred by a program user to the program controller. CONSTITUTION:The directory is provided with information indicating whether a program existing in the directory is released to its program user or not, the program user is provided with a determination right for determining whether the program existing in the directory is released to the program user or not and the number of directories including programs to be released to the program user are simultaneously restricted up to '1'. Plural subdirectories having the same name are allowed to exist in the same hierarchy of the directories under these three conditions and the program existing in the directory determined by the program controller is released to the program user. |
