Abstract
The present invention is directed to time-sharing computer system which includes a host computer system which operates in response to a host TSS command, a terminal computer system which is connected to the host computer system through a line and operates in response to a terminal TSS command, and a plurality of terminals which are connected to the terminal computer system. In this time-sharing system, the data processing in a terminal computer in response to a terminal TSS command input and the subsequent data processing in the host computer system in response to a host TSS command input can be carried out freely when the terminal is in a state of interaction with the host computer, without carrying out an end command of the host TSS a mode exchange operation. For this purpose, the system adopts the concept of a multiplexed TSS, which enables plural sessions to be simultaneously executed by the host computer system and the terminal computer system.
