ADDITIONAL FEATURES OF COBOL

Computers are sophisticated electronic machines designed to solve problems. A computer solves a problem by performing (or executing) a sequence of instruc tions (or statements) referred to as a program. Not only must the program list every step necessary to solve the problem, but it also must be written in a lan-guage that the computer can understand." Such languages are known as pro. gramming languages. COBOL is one of these programming languages. In this text. you will learn the skills necessary to write computer programs using COBOL as the language.

COBOL is an acronym for Common Business Oriented Language, the com-puter programming language most widely used for writing business programs. In this chapter, we will present some background information on computer programming in general and the development of the COBOL programming lan-guage in particular. We will also discuss the program development life cycle, which, if followed, makes software development efficient.
