COBOL 85 for Programmers by Jim Inglis

A concise, comprehensive introduction to the l985 ANSI and ISO Cobol standard. Treatment incorporates comparisons to the l974 standard. This is the first textbook to present Cobol programs in lower-case letters with reserved words in bold type. Begins with the language's file organization and access methods, introduces indexed files at an early stage, and treats file handling in detail. Appendixes provide a guide to details of Cobol syntax, reserved words, and language formats.
