An application development platform

ABSTRACT

While APL was a highly productive system for personal computing and application development when it was introduced, it is lacking nowadays in the areas of programming-in-the-large and user interface construction. The design and implementation of a new Application Development Platform (ADP) is described. The ADP frees the programmer from user interface concerns, and frees the application from device specific code. The ADP ensures consistent user interfaces based on state-of-the-art window techniques. Together with the underlying APL language, a software repository (Logos) and a data handling facility (ViewPoint®) the ADP is part of a full application environment. The paper describes the underlying principles of our ADP. We also present a small worked out example comparing a traditional toolbox with the ADP.
