If you're ready to start using Clipper to its full potential, there's no better guide than The CA-Clipper Interface Handbook. It has all of the practical information you need to realize the power and flexibility of the Clipper 5.3 development environment.
Authors John Paul Mueller and BJ Walsh use a multitude of working code examples to illustrate methods for interfacing Clipper with popular software packages, C and assembly language routines, networking programs, and graphics displays.
In addition to providing complete encyclopedic listings of Clipper commands and functions, Mueller and Walsh show you how to develop C and assembly language extensions; create new Clipper functions; speed up your applications by adding math coprocessor support; interface Clipper to peripherals; create add-on libraries; add mouse support to Clipper; customize Clipper to your computer and optimize Clipper performance.
You'll also learn how to use object-oriented programming techniques to create your own classes within Clipper and gain control over your display by writing your own display driver.
