Visual COBOL
Forget what you think you may know about COBOL. Even though the language is more than 50 years old, COBOL applications still reign in the world of enterprise IT. With billions of transactions executed every day and often running behind the scenes, COBOL systems touch many aspects of our daily lives. Your mission: To start a new era of innovation powered by modern tools that bridge COBOL systems to the world of Java and .NET. Brought to you by Micro Focus (www.microfocus.com), the leader in COBOL development tools, this book is written for the COBOL, Java and .NET developer. Key features include: A simplified real-world example to illustrate key concepts; an explanation of the .NET and Java object models for the COBOL developer; an introduction to COBOL for the Java or .NET developer; a complete reference to the new syntax for Visual COBOL; and a free student development tools license integrated within Visual Studio and Eclipse. The author, Paul Kelly, has worked at Micro Focus for over twenty years. He started as a technical author before moving into software development. Paul worked on Visual COBOL for 10 years between 2002 and 2012, initially on Visual Studio development, then later on Eclipse, before changing roles again to work as an architect developing a cloud-based SaaS offering for Micro Focus.
Beginning COBOL for Programmers
Beginning COBOL for Programmers is a comprehensive, sophisticated tutorial and modular skills reference on the COBOL programming language for established programmers. This book is for you if you are a developer who would like to—or must—add COBOL to your repertoire. Perhaps you recognize the opportunities presented by the current COBOL skills crisis, or are working in a mission critical enterprise which retains legacy COBOL applications. Whatever your situation, Beginning COBOL for Programmers meets your needs as an established programmer moving to COBOL. Beginning COBOL for Programmers includes comprehensive coverage of ANS 85 COBOL features and techniques, including control structures, condition names, sequential and direct access files, data redefinition, string handling, decimal arithmetic, subprograms, and the report writer. The final chapter includes a substantial introduction to object-oriented COBOL. Benefiting from over one hundred example programs, you’ll receive an extensive introduction to the core and advanced features of the COBOL language and will learn to apply these through comprehensive and varied exercises. If you've inherited some legacy COBOL, you’ll be able to grasp the COBOL idioms, understand the constructs, and recognize what's happening in the code you’re working with. Today’s enterprise application developers will find that COBOL skills open new—or old—doors, and this extensive COBOL reference is the book to help you acquire and develop your COBOL skills.
