Murach's Mainframe COBOL


Book Description

This is the latest edition of our classic COBOL book that has set the standard for structured design and coding since the mid-1970s. So if you want to learn how to write COBOL programs the way they're written in the best enterprise COBOL shops, this is the book for you. And when you're done learning from this book, it becomes the best reference you'll ever find for use on the job. Throughout the book, you will learn how to use COBOL on IBM mainframes because that's where 90% or more of all COBOL is running. But to work on a mainframe, you need to know more than just the COBOL language. That's why this book also shows you: how to use the ISPF editor for entering programs; how to use TSO/E and JCL to compile and test programs; how to use the AMS utility to work with VSAM files; how to use CICS for developing interactive COBOL programs; how to use DB2 for developing COBOL programs that handle database data; how to maintain legacy programs. If you want to learn COBOL for other platforms, this book will get you off to a good start because COBOL is a standard language. In fact, all of the COBOL that's presented in this book will also run on any other platform that has a COBOL compiler. Remember, though, that billions of lines of mainframe COBOL are currently in use, and those programs will keep programmers busy for many years to come.

Database Design and Programming for DB2/400


Book Description

Database Design and Programming for DB2/400 is a comprehensive introduction to the design and implementation of application databases on IBM's AS/400. This clear and authoritative text teaches you the following essential skills: Coding Data Description Specifications (DDS) for physical and logical files, entering CL commands to create DB2/400 files from DDS, using field reference files, accessing database files from RPG IV, RPG/400, COBOL/400, and other AS/400 high-level languages, the Relational Database Model as a foundation for DB2/400 and database design, practical database design and data modeling, using SQL/400 to define and access database files, advanced DB2/400 features (including commitment control, the Open Query File command, database constraints, triggers, distributed database access, and others), database security, and data backup and recovery. Paul Conte, a leading DB2/400 authority with extensive application development experience, provides easy-to-follow instruction in the proper way to create efficient, flexible databases on the AS/400. His explanations and advice assure that you'll handle your design and coding challenges with confidence and professional-level techniques. This book provides complete coverage of both DDS, the traditional approach to defining DB2/400 files, and of SQL/400, the industry-standard database language that is IBM's strategic language for the future of DB2/400. With this text, you can be sure of handling not only existing application databases, but also developing new SQL/400 databases. These skills will put you in the forefront of AS/400 application developers. Database Design and Programming for DB2/400 also provides an excellentintroduction to practical database design techniques. You get a solid introduction to the relational database model, which underlies the whole DB2/400 architecture and the SQL language. On that foundation, the book explains a step-by-step method of modeling an organization's database requirements and developing a design for the necessary database files. The text is designed for college-level courses and for independent study. Each chapter has numerous examples and exercises. The material is organized into four parts - DDS, database design, SQL, and advanced DB2/400 features - so you can focus on particular topics as needed. Appendices provide extensive reference material. You can use the book as your single DB2/400 resource, eliminating the need for many IBM manuals. You will find Database Design and Programming for DB2/400 immediately useful, whether you're just beginning to learn DB2/400 or you are an experienced developer. You will turn to this book time and time again for advice on the best way to design and program DB2/400 databases.

IMS for the COBOL Programmer: Data communications and message format service


Book Description

The second part of IMS for the COBOL Programmer is for MVS programmers only. It teaches you how to handle online programs that access IMS databases and run under the data communications (DC) component of IMS. This book also covers Message Format Service (MFS). MFS acts as an interface between the format of messages at a terminal and the I/O formats in your programs. So you'll learn how to use MFS to create formatted screens that are easy for operators to use. And you'll learn what tasks you can handle through MFS instead of having to code for them in your DC programs.
