PURPOSE:To easily allow a controller on a high-order to inhibit a user on a low-order from using a specific resource when it is necessary or using the resource more than a fixed quantity. CONSTITUTION:When a user is a group member (x), virtual space maximum size 300 MB and usable permanent file resource names DD, EE are stored in a working area. A user control file information reference part refers the resource control information of a immediate high-order group successively up to the group on the most significant level in accordance with a group user chain, executes AND operation between the referred resource control information and information in a working area, narrows the resource control information, and then stores the narrowed information in the working area again. When the user is the group member (x), AND operation between respective resource control information of the just high-order group E, its high-order group B and the most significant level group A and that of the group member (x) is calculated. Consequently, only 100 MB as a virtual space maximum area and DD as a usable permanent file resource name are left in the working area. |
