ABSTRACT:
In controlling data by a computer, pointers are represented by addresses in the real memory space RM in the real memory space RM and by addresses in the virtual memory space IM and by addresses to said real memory space RM in the virtual memory space, and nodes in the virtual memory space IM are indirectly referenced from the nodes in the real memory space RM so that data of a structure in which the nodes are linked by pointers are represented across the real memory space RM and the virtual memory space IM. The data of the structure in which the nodes are linked by the pointers are shifted between the real memory space RM and the virtual memory space IM with the list structures U.sub.0, U.sub.1, U.sub.2, U.sub.10 employing the link information as units. In this manner, the virtual memory technique may be efficiently realized in the case of the list structure data which are basic and indispensable in the field of symbol manipulation such as artificial intelligence, formula manipulation or natural language manipulation.
