Abstract
PURPOSE:To attain efficient random access by storing a random access memory with address information for access to a mass storage file. CONSTITUTION:For an area where address information is stored, addresses a- a+(m-1) are assigned in random access memory DM. At this time, this area is previously filled with special symbols. The data storage address starts at address b of random access file MM. Data are rgistered at address b of MM by giving key k1. In this case, value b is written at address a+(k1-1). Then, key k2 is supplied to register data at address b+(length of single data) of MM. At address a+(k2-1), b+(length of single data) is written. Similarly, n data are written up to address b+nX(length of single data).
