Practical Usage of MVS REXX provides a concise and complete source of information for the development of applications using the REXX language - IBM's systems application architecture procedural language. The book adopts a highly practical approach and includes many lists and diagrams to make finding the relevant information as easy to find and use as possible. It particularly emphasises the interfacing capabilities of REXX. Both beginners and experts will find the book useful. Beginners are led through the steps required to develop REXX applications via a series of worked examples, and experts will find a complete and easy reference to the language.

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.

Packed with current data and the latest methods, this hands-on reference shows you how to use the two major mainframe interface products--MVS Time-Sharing Option (TSO) and Interactive System Productivity Facility (ISPF)--to create and store data, print documents, and perform data management functions.

This book is intended to support ISPF application programmers to become professional in the smart programming of ISPF applications using the REXX language. The contents are presented in a modular manner to suit reading with heterogeneous ISPF programming knowledge. The following topics are covered: Introduction to the programming language REXX as well as to ISPF programming, data processing in ISPF applications, use of messages, panels, skeletons, tables, ISPF variables and an introduction to creating and applying edit macros. Each theme is vividly illustrated by programming examples. The Smart ISPF Utilities contain some very useful programming aids that are often useful when programming ISPF applications. The book serves as a textbook as well as a manual for daily work. Many cross-references are included as well as an extensive index. Moreover, the author gives many helpful hints and tips on smart ISPF programming practices. The Smart ISPF Utilities contain many useful programming aids.
