PURPOSE:To execute the processing in accordance with a priority order, by deciding a processing ratio among plural processing procedures so that a sentence being in the course of a processing procedure of ''1'' is executed by the number corresponding to said processing ratio, in case of multiprocessing of plural processing procedures by a microcomputer of an interpreter system. CONSTITUTION:When a microcomputer is started, it sets a value of a processing ratio to registers 121, 131, 141-. Subsequently, the microcomputer reads out a number of the next processing procedure to be executed, from a proposed example table 11. The microcomputer decides immediately whether the fetched sentence is an executable sentence or not. In case of being executable, processing of its sentence is executed. Subsequently, the microcomputer sets an address of a memory in which the next sentence to be processed is stored, to the register 121. Also, ''1'' is added to the register 123, which shown the number of sentences executed after shifting of the processing. |
