Abstract

PURPOSE:To set an address at the boundary between a program area and a data area by means of a switch provided to a central processor. CONSTITUTION:In case a data area 2 is short and a program area 3 is excessive, the area 2 is pressed down by a switch 7 to decrease the area 3. Inversel, in case the area 3 is short and the area 2 is excessive, the area 2 is pressed up to increase the area 3. With installation of such switch, the address is set at the boundary between the data and program areas.
