    The Application System/400™ (AS/400™) is IBM'S new generation of midrange computers. Incorporating many characteristics of the System/36 and System/38, the AS/400 has more power and capability than those predecessors. In this issue, the first six papers provide technical information on the design and structure of the AS/400 and show how IBM Business Partners and the user community pe... View full abstract»

    The operating system for Application System/400™ (AS/400™) provides an unprecedented breadth of function and system services in a single, integrated system. The majority of functions are implemented on top of an abstract, high-level machine interface in a hardware-independent manner, using many architectural characteristics normally associated with poor performance. Despite these arc... View full abstract»

  • The Application System/400 help facility—-sign philosophy and considerations

    Publication Year: 1989, Page(s):424 - 442
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2886 KB)

    The design of the Application System/400™ (AS/400™) system help facility was based on the philosophy that users must be able to quickly access the specific information needed to complete their immediate task. This philosophy, reinforced by experience with help information on earlier IBM systems, resulted in a modular help facility that provides two major types of assistance discussed...

    Object-oriented programming involves a new way of thinking about and programming applications. The thought process and techniques are introduced through a discussion of the language Smalltalk and through an illustrative example. These concepts are extended to a hybrid functional language, object-oriented system, KEE®, and illustrated through the use of knowledge-based system examples. View full abstract»

    This paper presents a design for a message management system that reduces the coding effort for the application developer, gives the user greater control over the treatment of application messages, and eliminates many problems of translation. Any message may be directed to one or more devices (screen, printer) and/or files (log, activity), with the ability to exclude message elements (e.g., date a... View full abstract»
