COBOL for the 21st Century: A Review
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 facilitate business data processing. Despite its age, COBOL is still running a large number of the world's business data applications, and it is likely to remain a viable language in the years ahead.
However, COBOL has also evolved over time, incorporating new features and standards to meet the changing needs of the industry. To learn COBOL effectively, one needs a comprehensive and up-to-date textbook that covers both the fundamentals and the latest developments of the language.
One such textbook is COBOL for the 21st Century, written by Nancy Stern, Robert Stern, and James Ley. This book, now in its 11th edition, is designed to teach COBOL programming to students and professionals who have little or no prior experience with the language. The book covers both structured and object-oriented programming techniques, as well as interactive and batch programming with sophisticated file processing methods.
The book also introduces valuable information processing and systems concepts that will help programmers interact with users and systems analysts when designing programs. The book uses program planning tools such as pseudocode and hierarchy charts to make program logic more structured, modular, and top-down. The book also provides useful techniques for maintaining and modifying older "legacy" programs.
The book is updated to reflect COBOL 2008, where appropriate, and includes a chapter on the Report Writer Module, which is a powerful tool for generating formatted reports. The book also comes with a companion website that features a syntax reference guide, data sets for all programming assignments, and all programs illustrated in the book.
The book has received positive reviews from both instructors and students who have used it in their courses. The book is praised for its clear and concise explanations, its practical examples and exercises, its effective learning tools, and its comprehensive coverage of COBOL topics.

COBOL programs can run on a variety of hardware and software environments, such as mainframes, minicomputers, microcomputers, UNIX, Windows, Linux, and more. This makes COBOL a versatile and adaptable language that can handle diverse business applications.
Another benefit of COBOL is its readability and self-documentation. COBOL programs use English-like words and phrases that make the code easy to understand and follow. COBOL also supports comments and documentation sections that help programmers explain the purpose and logic of their programs. This makes COBOL programs easier to maintain and modify by other programmers.
A third advantage of COBOL is its reliability and performance. COBOL programs are known for their accuracy and efficiency in processing large amounts of data. COBOL also has built-in features that handle errors and exceptions gracefully, such as the ON SIZE ERROR clause and the EXCEPTION-STATUS data item. These features help programmers avoid runtime errors and ensure the quality of their programs. Here are some more paragraphs that I wrote for the article: A fourth advantage of COBOL is its integration and interoperability with other languages and technologies. COBOL programs can communicate and exchange data with other programs written in different languages, such as Java, C, C++, and more. COBOL also supports web development and web services, such as XML, SOAP, and REST. These features enable COBOL programmers to create modern and dynamic applications that can interact with the internet and other systems.
A fifth advantage of COBOL is its availability and accessibility of resources and support. COBOL has a large and active community of programmers, users, and organizations that provide guidance, assistance, and training for COBOL development. There are also many online forums, blogs, websites, books, and courses that offer valuable information and tips on COBOL programming. Additionally, there are many free and open source COBOL compilers and tools that can help programmers create and test their programs.
In conclusion, COBOL is a powerful and relevant programming language that has many benefits for business data processing. With COBOL for the 21st Century, you can learn how to use COBOL effectively and efficiently to create high-quality and robust programs that can run on various platforms and systems. You can also learn how to use COBOL in conjunction with other languages and technologies to create innovative and interactive applications that can meet the demands of the 21st century. I have written some more paragraphs for the article. Here they are: One of the challenges of COBOL programming is to keep up with the changing standards and features of the language. COBOL has undergone several revisions and enhancements over the years, resulting in different versions and dialects of the language. Some of the most notable versions are COBOL-60, COBOL-68, COBOL-74, COBOL-85, COBOL 2002, and COBOL 2008.
Each version of COBOL introduces new syntax, keywords, data types, statements, and functions that improve the capabilities and performance of the language. However, each version also has its own compatibility and portability issues that may affect the execution and maintenance of existing programs. Therefore, it is important for COBOL programmers to be aware of the differences and similarities among the various versions and dialects of COBOL.
COBOL for the 21st Century helps programmers cope with this challenge by providing a thorough and systematic comparison of the major versions and dialects of COBOL. The book explains the historical background and rationale behind each revision and enhancement of the language. The book also highlights the advantages and disadvantages of each version and dialect, as well as the best practices and recommendations for using them.
The book also covers some of the most popular and widely used extensions and implementations of COBOL, such as Micro Focus COBOL, IBM Enterprise COBOL, GNU COBOL, Visual COBOL, NetCOBOL, and more. The book shows how these extensions and implementations add new features and functions to COBOL that make it more compatible and interoperable with other languages and technologies.
By reading COBOL for the 21st Century, you can learn how to write COBOL programs that conform to the current standards and specifications of the language.
