COBOL was first introduced in 1959, and its popularity soared in the 1960s and 1970s, as businesses began to adopt mainframe computers for data processing and business applications. Today, COBOL remains a crucial part of many mainframe environments, with an estimated 85% of the world's business applications still running on COBOL. The reasons for its enduring relevance are:

COBOL is a column-dependent language. If you have ever tried to copy code from a poorly scanned PDF, you know the pain. A single misalignment in the "Area A" or "Area B" columns causes compilation errors that will drive you insane. Murach’s physical books (and their official digital editions) preserve this formatting perfectly. Bootleg scans often do not. If you acquire a high-quality digital copy of

First, let's clarify exactly what you are looking for. The full title of the book is typically "Murach’s Mainframe COBOL" (often subtitled or associated with "Murach’s OS/390 and z/OS COBOL" depending on the edition). Authored by Mike Murach and his team of mainframe developers, this book is rarely found in modern bookstores. It is a relic of the late 1990s and early 2000s—a period when the Y2K crisis made COBOL programmers the highest-paid mercenaries in the tech world.

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.
