Abstract

A method for use with a computer which directly transfers incoming data into the computer memory. A functional address contained in a received message is used to index a pointer in a vector table. The indexed pointer addresses an input control block associated with the functional address. The input control block is used to control the flow of data into the computer memory. The input control block also controls access to the computer memory for subsequent messages having the same functional address.
