Abstract
PURPOSE:To advance the period of delivery without the need to develop a new channel or the remodel a channel, by converting a group of channel control words into those different in format and by exercising input/output control by using the converted channel control word group. CONSTITUTION:When to receive data from card reader 8, CPU3 sends to channel 5 the starting address of main storage device 4 where channel control word group describing control information is stored. While using this starting address, channel 5 reads word group CCB2 out of device 4 directly and stores it in the internal storage temporarily. Word group CCB2 is then converted into word group CCB2' differing in format with word group CCB1 used by CPU1. This word group CCB2' is used to transfer various pieces of information to respective registers, and then channel 5 starts the control over the input operation for data from card reader 8.
