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.
