The Modular Application Customizing System

MACS is a development tool intended to address the practical problem of mass producing standard small-business computer applications in a variety of configurations. This paper has described the current implementationo f the tool,w hich consists of four elements: support system, driver, master model, and industry-specific changes. The support system consolidates master model and industry changes to form the industry model, which in turn is processed by the driver,u sing services of the support systemi,n a customizing run to produce tailored application packages. The driver, master model, industry changes, and customizing run are defined by the specific implementation; the one described here has been used for several years to produce System/32 and System/34 programming packages.
