| Feature | Description | | :--- | :--- | | | Teaches the industry-standard methods for structured design and coding, pioneered by Murach staff in the mid-1970s and now used in the best mainframe shops. | | Hands-On Exercises & Projects | Includes practical end-of-chapter exercises and projects that challenge you to develop complete programs. These materials are also available for free download. | | Practical "How-To" Approach | Focuses on job-ready skills like writing reports, updating files, and crafting interactive programs, not just theoretical concepts. | | Efficiency-First Design | Covers how to be an effective maintenance programmer, which accounts for 70% or more of the programming work done in mainframe shops. | | Complete Ecosystem of Tools | Includes a Student Workbook, PowerPoint slides for instructors, chapter and section tests, and the complete source code for all programs in the book. | | Practical Debugging Skills | Exercises include programs with pre-built compile-time and run-time errors for students to find and correct, building real troubleshooting skills. | | | Hands-On Exercises & Projects | Includes

: You do not need a multi-million dollar IBM z/Architecture mainframe to practice. Use open-source projects like GnuCOBOL to compile and run the exercises found in the book on your local Windows, Mac, or Linux machine.

Programs frequently read sequentially sorted transaction files to generate flat reports. For random, rapid access to data records, IBM’s allows files to be indexed by key fields (like an Account Number), letting programs read, write, or update any record instantly without parsing the entire dataset.

Before writing code, you must understand where it executes. The book covers:
