This IBM Redbook introduces the IBM Application Development Tools for z/OS and OS/390. The first chapter provides a high level overview of each of the products, suitable for any person that requires an introduction to these capabilities. The remainder of the book delivers more technical information, including numerous examples of some of the most commonly used functions of each tool and scenarios of how the tools could be used in an everyday customer environment. The specific application development tools for z/OS and OS/390 covered in this book are: IBM File Manager for z/OS and OS/390, Version 4, Release 1 IBM Fault Analyzer for z/OS and OS/390, Version 4, Release 1 IBM Application Monitor for z/OS and OS/390, Version 2, Release 1 IBM Workload Simulator for z/OS and OS/390, Version 1, Release 1 IBM Debug Tool for z/OS and OS/390, Version 4, Release 1

This IBM Redbook describes the IBM Application Development Tools for z/OS and OS/390 and includes scenarios that show how to use the tools to recognize, locate, and fix errors in application programs. Part 1 describes the five program products that make up the suite and product integration : -> IBM Fault Analyzer -> IBM File Manager -> IBM Debug Tool -> IBM Application Monitor -> IBM Workload Simulator. Part 2 walks you through detailed scenarios that demonstrate how the tools can be used in a practical, day-to-day manner. Part 3 contains code samples, reports and listings, and examples that are too large to include in the chapters.

Vast numbers of otherwise fully functional application programs are currently unable to interpret the abbreviated date values they contain as belonging to any century but the twentieth. The need to approach the daunting task of identifying, analyzing, and eliminating this limitation in a systematic and efficient manner has led IBM to offer a complementary assortment of products and services collectively known as VisualAge 2000. The guidelines, products, and services that constitute VisualAge 2000 are intended to support customers in their own efforts to tackle the problems posed by the use of abbreviated date fields in their application programs. This book examines two of the products available in the VisualAge 2000 collection designed to address the requirements of system programmers and application developers engaged in identifying and correcting abridged date fields in their application programs in an OS/390 environment: Maintenance 2000 Assists in Year 2000 impact analysis of host applications. The Millennium Language Extensions to COBOL for OS/390 & VM Provides automatic century windowing for specified date fields. In addition to providing an introduction to the functionality available within Maintenance 2000, this book uses a sample application as the basis for a concrete demonstration of how the product can be used to perform the tasks of date identification, Year 2000 impact analysis, and result management. The actual results of the Year 2000 impact analysis process are then used as the basis for

This redbook, 'VisualAge 2000 Test Solution: Testing Your Year 2000 Conversion', demonstrates the VisualAge 2000 Test Solution in action, through a series of tutorials. It is for managers or executives who wish to have a clearer understanding of Year 2000 testing, applications programmers who are involved in testing, and system programmers who support the applications programmers. Part 1 sets out the framework of the VisualAge 2000 Test Solution, describes the tools that are used in the redbook, and describes how to install the sample files. Part 2 presents the tutorials, where each tutorial works through one of the steps in the Test Solution. The tutorials provide detailed instructions for using the nominated tools. By working through the tutorials, you will have a much clearer understanding of what is involved in Year 2000 testing. This edition of the redbook is for OS/390 or VSE users running COBOL or PL/I programs, and using an OS/2- or Windows NT- or Windows 95-based work station. Note that MVS is also supported by the book. MVS users should assume that for 'OS/390' they can read 'MVS', except in product names. A CD-ROM is provided with the redbook. The CD-ROM contains sample programs, data, and JCL, to work through the tutorials. As well, the CD-ROM contains a 'slide-show' demonstration, which runs under Windows and Win-OS/2. The demonstration shows the various tools in action, and is a quick introduction to the tutorials, or for people who do not have access to a particular tool. The tools used extensi
