Practical Usage of ISPF Dialog Manager

Practical Usage of ISPF Dialog Manager is a concise and comprehensive source of information for the development of applications using IBM's Dialog Management package. Dialog Manager is a vehicle for implementing dialogue applications (such as PDF - Program Development Facility) and is very well suited to the implementation of individual dialogue systems and those systems which are required to run from the TSO/ISPF environment. It is also ideally suited for prototyping.
This book is intended for both beginners and experts. With its carefully chosen blend of theory and practice, and extensive use of examples and case studies, this book will provide an invaluable guide to all those needing to learn about or using the ISPF Dialog Manager.
