IMS for the COBOL Programmer: Data base processing with IMSThis how-to book will have you writing or maintaining batch DL/I programs in a minimum of time -- whether you're working on an MVS or a VSE system. Yet it doesn't neglect the conceptual background you must have to work confidently with DL/I. What's more, this book has 3 chapters that describe in detail how DL/I databases are stored and accessed, so you'll know how to program more logically and efficiently for the type of database you're processing. This critical information isn't found in other IMS books or the IBM manuals. |
