1 gru 1983 · COBOL is used for developing business, typically file-oriented, applications. It is not designed for writing systems programs. You would not develop an operating system or a compiler using COBOL. COBOL is one of the oldest computer languages in use (it was developed around the end of the 1950s).
This project is a set of training materials and labs for COBOL on z/OS. The following books are available within this repository. To get started, follow the steps in their respective READMEs.
COBOL is designed around decimal arithmetic, unlike most languages that use a binary internal representation. The COBOL spec calls for very precise fixed point decimal calculations, an aspect of the language that has been well regarded in financial sectors. COBOL also allows for USAGE BINARY, but leans towards decimal (base-10) representations.
COBOL was the first widely used high-level programming language. It is an English-like language which is user friendly. All the instructions can be coded in simple English words. COBOL is also used as a self-documenting language. COBOL can handle huge data processing. 1. OVERVIEW
COBOL stands for Common Business-Oriented Language. The US Department of Defense, in a conference, formed CODASYL (Conference on Data Systems Language) to develop a language for business data processing needs which is now known as COBOL. COBOL is used for writing application programs and we cannot use it to write system software.
After completing this chapter, you will understand the three COBOL divisions used to identify the program and its files (Identification, Environment, and Data Division).
