COBOL Programming by M. K. Roy and Debabrata Ghosh Dastidar: A Classic Textbook for Learning COBOL
COBOL is one of the oldest and most widely used programming languages in the world. It was developed in the late 1950s and early 1960s to provide a common business-oriented language for various computer systems. COBOL stands for Common Business-Oriented Language and it is designed to handle data processing tasks such as payroll, accounting, inventory management, and so on.
COBOL Programming by M. K. Roy and Debabrata Ghosh Dastidar is a comprehensive textbook that covers the basic and advanced features of COBOL. It was first published in 1982 by Tata McGraw-Hill and has been revised and updated several times since then. The book has 496 pages and consists of 18 chapters that cover topics such as data types, control structures, file handling, subprograms, tables, report writing, sorting, merging, indexed files, sequential access methods, direct access methods, relative files, VSAM files, database management systems, structured programming, modular programming, object-oriented programming, and graphical user interface programming.
The book is suitable for students, programmers, and professionals who want to learn or improve their skills in COBOL. It provides clear explanations, examples, exercises, and projects to help the readers master the concepts and techniques of COBOL programming. The book also includes a CD-ROM that contains the source codes of the programs in the book, a COBOL compiler, and a COBOL debugger.
COBOL Programming by M. K. Roy and Debabrata Ghosh Dastidar is a classic textbook that has been used by thousands of students and professionals over the years. It is one of the best resources for learning COBOL and applying it to various business problems.
COBOL is not only a historical language, but also a living one that is still widely used in many business domains. COBOL applications help run payroll programs, manage government pension funds, operate banking systems, manage hotel bookings, book airline tickets, and much more[^1^]. Estimates largely agree COBOL systems support more than $3 trillion in daily commerce[^2^].
COBOL is a domain-specific, or specialist, language. In other words, it is designed to solve problems in a particular area of application. COBOL excels at transaction processing, data manipulation, and report generation. It has a simple and English-like syntax that makes it easy to read and maintain. It also has features that support structured and modular programming, as well as object-oriented programming since 2002[^1^].
COBOL can run on various platforms, such as mainframes, servers, desktops, and mobile devices. It can also interact with other languages and technologies, such as Java, .NET, XML, web services, and databases. COBOL applications can be modernized and integrated with new systems using tools and frameworks provided by vendors such as Micro Focus[^2^].
COBOL is a versatile and powerful language that has proven its value and reliability over the decades. It is still evolving and adapting to the changing needs of the business world. COBOL programmers are in high demand and can find rewarding careers in various industries. Learning COBOL can be a great way to enhance your skills and expand your opportunities. ec8f644aee
