Abstract

This articles describes a system that enables users to operate mainframe computers with workstation user interfaces. This system has following characteristics: 1. The mainframe application programs can be used without any modifications. 2. The mainframe applications are accessed from workstation user interfaces via the terminal emulator. 3. The workstation program provides new user interfaces. 4. The profile, a file on the workstation, describes the relationships between the interfaces of the mainframe applications and workstation programs. 5. This system converts the interface by referring to this profile.

System for Accessing a Mainframe From a Workstation User Interface

This articles describes a system that enables users to operate mainframe computers with workstation user interfaces. This system has following characteristics: 1. The mainframe application programs can be used without any modifications. 2. The mainframe applications are accessed from workstation user interfaces via the terminal emulator. 3. The workstation program provides new user interfaces. 4. The profile, a file on the workstation, describes the relationships between the interfaces of the mainframe applications and workstation programs. 5. This system converts the interface by referring to this profile.

In the traditional way, it is impossible to provide user interfaces conforming to SAA/CUA. To create new user interface modules on the workstation, the mainframe applications themselves must be rewritten.

This system, which also conforms to SAA/CUA user interfaces, was invented to improve the usability without changing the mainframe applications. This system consists of six parts, as shown in the figure. 1. MFI Terminal Manager performs terminal operations, such as typing and reading data on the terminal, by utilizing the Application Programming Interface (API) of the terminal emulator. 2. MFI Terminal Profile Analyzer analyzes the MFI terminal profile, which defines how to operate on a certain scrollable panel of the mainframe applications. 3. User Interface Mapping Manager makes the conversio...
