ABSTRACT:
In an input/output process device for controlling data transfer between a central processing unit and an input/output device through a channel by use of any of a plurality of input/output control devices connected to the input/output device, a memory unit is disposed so as to store information representing the address of the input/output control device in association with an identification number of the channels connected to the input/output control device. When selecting the channel for data transfer, the input/output process device reads out the information representing the address of the input/output control device from the memory unit and generates the address for the input/output control device on the basis of the information read out.
