Debugging, Protection When Errors Arise

Abstract

Where there is programming, there are errors. This rule has proved itself true over the course of the past half century. Even in programs that have been maintained for years, new errors are always being discovered. (We shall pass over in silence such programs as Excel and Word, where the implementation of new functions appears to have priority over the debugging process.) The purpose of this chapter is not, however, to quibble about the quality of the software at hand, but to show you how you can make yours better. Perhaps you will even come to appreciate that even Microsoft is not perfect.
