REXX is a general purpose language which is easy to learn. It contains an extensive library of powerful functions which greatly reduces the amount of coding necessary to write applications. The use of REXX in a wide range of environments simplifies the writing of applications to run under different hardware and operating systems, and its expansibility allows other components to make sure of REXX facilities and vice versa. Practical Usage of TSO REXX provides a concise source of information for the development and implication of applications using the REXX language. The author adopts a practical approach, using lists and diagrams to illustrate relevant points. This third edition, (previously titled Practical Usage of MVS REXX), has been revised to include the new REXX features introduced for the OS/390 TSO/E environment.

Implementing Practical DB2 Applications provides a concise source of information for the development and implication of applications using IBM's DB2 relational database package in the MVS environment. The book describes the flagship DB2 version, namely that implemented for the MVS operating system environment where DB2 operates with the MVS transaction processing subsystems: CICS, IMS and TSO.
The book is intended for both beginners and experts. It describes how the various components of SQL are used to provide practical applications.
Containing tips and notes that were discovered the hard way - through hands on experience - this book will be welcomed by all those looking to implement applications in DB2.

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.
