Are you maintaining a COBOL legacy system? If so, there\`s a good chance you need to know something about IMS (or DL/I, on a VSE system), the leading database system before DB2 came into prominence. And you can learn what you need to know the same way programmers have for a dozen years, by using our DL/I text. Although the printed version is no longer available, you can still get the content on CD. With all the text, illustrations, and sample code to guide you, you\`ll be handling batch DL/I programs in no time. You\`ll learn the COBOL elements for working with DL/I databases, why error processing is a must, how to use secondary indexing, how to process logical databases or databases with logical relationships, and a little something about coding online programs using IMS DC or CICS (you\`ll need one or more of our other books, though, to gain a complete set of DC or CICS skills). You\`ll even find out how different types of DL/I data bases are stored and accessed, so you can program more logically and efficiently for the type you\`re working with. That\`s information you can\`t find anywhere else! ISBN 9780911625301
