Provides the reader with a comprehensive array of topics on the most widely used MVS/COBOL productivity tools. Each chapter is devoted to a different area in an MVS/COBOL environment, presenting material previously unavailable to the general public or insufficiently documented. Some of these topics include dBUG AID, Interest, File-AID, Abend-AID, and others. Using practical examples and prototypes, this book demonstrates how to resolve problems efficiently in testing an application program; manage, store, and handle programs through a library system; do away with cumbersome IBM utilities by creating VSAM clusters and other on-line utilities; and more. Coverage of JCL complexities and solutions, as well as two chapters on CICS advanced programming concepts, are also included. An entire chapter is devoted to the widely used DB2.
