__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. What you’ll learn* The basics of COBOL and its control structures * How to declare and manipulate data, including tabular data * How to handle sequential, indexed, and relative files * How to SORT data and use Input and Output procedures * How to SEARCH tabular data * How to use contained and external subprograms to create modular programs * How to use the COBOL Report Writer * How to write ISO 2002 object-oriented COBOL programs Who this book is for This book is for established programmers looking for a COBOL tutorial and modular skills reference in one handy book. Whether you have inherited some legacy COBOL and need to maintain it, or you have a fresh COBOL project in front of you, the tutorial and skills reference will help you succeed in COBOL.

OO-COBOL Beginning COBOL for Programmersis a comprehensive, sophisticated tutorial and modular skills referenceon 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 you may be 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 Programmersincludes coverage of the latest COBOL featuresand techniques, including control structures, tabular data, sequential files, procedure divisions, string handling, decimal arithmetic, report writer, object-orientedCOBOL, and more. You'll receive extensive introductions to the core features of the COBOL language, and then find solutions about how to effectively deploy COBOL to build robust mission critical enterprise applications that talk to legacy enterprise applications or aspects of those applications. If you've inherited some legacy COBOL, you'll be able to grasp the COBOL idioms and recognize what's happening in the code you're working with. The death of COBOL has been predicted time and time again, yet COBOL still remains a dominant force at the heart of enterprise computing. In 1997, the Gartner group estimated that of the 300 billion lines of code in the world, 240 billion (80%) were written in COBOL, and that dominance is not greatly changed today. But there is a crisis on the horizon. While the number of COBOL programmers reaching retirement age has created a growing shortage, attempts to rewrite COBOL legacy systems in a more fashionable language have oftennot been successful or put aside for a number of reasons. Therefore, today's enterprise application developers - mostly skilled at C++, C♯ and Java - can find COBOL skills open new - or old - doors, and this handy reliable reference is a book that you can turn to for your COBOL skills Michael Coughlan.
