Title: The Innovations of James Lum

Introduction

James Lum is an accomplished inventor based in Redwood City, CA. He has made significant contributions to the field of technology, holding a total of 5 patents. His work primarily focuses on message processing systems and program isolation mechanisms, showcasing his expertise in computer systems.

Latest Patents

One of Lum's latest patents is a message processing system. This innovation involves a standardized message processing procedure invoked by an application program to generate informative messages. The system includes message repositories in files accessible to the message processor, with separate repositories for each supported national language. The application invokes the message processor, passing variable information for inclusion in a message. The message processor retrieves the message syntax and fixed fields from the appropriate repository, assembles the message using information from both the repository and the invoking application, and generates the final message. Additionally, a preprocessor can be utilized to generate the repository files and macros suitable for inclusion in application source files to invoke the message processor.

Another notable patent is a linkage mechanism for program isolation. This invention describes a computer system equipped with general-purpose registers, control registers, and access registers that contain information to allow address space capability. The linkage stack uses protected address space to store state information during program call and return operations. It contains information relating to state entries for saved information, as well as header and trailer entries to point to other linkage stack sections. A control register holds the pointer to the current linkage stack entry, which changes as the program call or return progresses through the stack.
