PURPOSE:To actuate a file save loading action for the entire data structure where the interrelationship is expressed via the address pointer type data at a high speed and with no dependence on the data structure, by using a structure definition table and a memory control table. CONSTITUTION:Both a structure definition table and a memory control table are read at first and the memories are allocated according to the memory sizes described in the memory control table. At the same time, the head address value of the control table is set at the value obtained in the previous tape state and then the memory address allocated this time is set as the head address. This processing is carried out with all memory allocating information on the control table. Then the data entering an actual memory area is read out for each block and written into the corresponding areas in the order of control tables. The type of the data structure is obtained from the control table and the position of the address pointer type data is obtained. Thus the desired address value is obtained.
