This IBM Redbook details the configuration and use of some of the features of IBM VisualAge COBOL Version 3. The mainframe application programmer can now use VisualAge COBOL to edit, compile, and debug an MVS application without even logging on to TSO. Although the programmer is working in a workstation environment, the source code remains on the mainframe, and the program is running in its target environment for debugging. IBM VisualAge COBOL provides a state-of-the-art graphical user interface for all the tasks involved in the development and maintenance of mainframe applications, including batch, DB2, CICS, and IMS applications. Additionally, using a modern development environment to maintain and develop mission critical batch and server applications will help your company retain skilled COBOL developers while attracting talented new programmers who are familiar with similar tools used in Java. This book introduces the reader to various development scenarios, showing how the Remote Edit/Compile/Debug model can help to increase the productivity of an application developer. Although written for VisualAge COBOL, this book can also be easily used as a reference for VisualAge PL/I.

This redbook details the configuration of a client/server environment consisting of IBM VisualAge COBOL, DB2 Universal Database, and TXSeries products on Windows NT. Installation and customization details as well as some application development techniques are covered. The book was written for those interested in the interaction of the above family of products when the applications are written in COBOL. Technical marketing, application development, and local area networking personnel will find this information particularly useful. The book guides the reader, step by step, in creating a working client/server environment, for both application development as well as application execution. This environment can be used for demonstration or as a reference when setting up a similar environment for productive use. Several practical examples are used throughout the book. Because the main focus of the book is on the environment and the interaction of the products, the program samples are kept as simple as possible. First, we provide the setup of an environment that only includes remote data access. Once the sample program is running, you know that your DB2 Universal Database (UDB) is installed and configured correctly. You can then go on to the next step, in which we add TXSeries to this scenario. We explain the environment by means of a CICS server program that accesses a DB2 database. This server program is called by a 3270 CICS client program as well as an external call interface (ECI) client program with a graphi

This redbook details the configuration of the communication between workstation and host systems to use the new remote edit, compile, and debug component of VisualAge for COBOL Version 2.0 on Windows NT. Installation details are covered as well as application development techniques. Several practical examples are provided on diskette for you to install on your host and use with this redbook. This redbook also gives you an introduction to developing host applications from a workstation environment, explains in detail how to configure your workstation for communicating with the host via TCP/IP, and the use of the NFS product, NetManage Chameleon NFS/X for Windows 6.0. This redbook also describes how to use remote edit, compile, and debug for a batch COBOL application and a batch DB2 application, contains the details on configuring APPC on NT, and shows you how to use VSAM for the workstation for local and remote data access through the SMARTdata Utilities. Application development knowledge in an MVS environment is a prerequisite for the MVS portions of this book. Knowledge of COBOL programming and NT is presumed. Some knowledge of TCP/IP and APPC would also be helpful.

This redbook details the configuration of the communication between workstation and host systems to use the new remote edit, compile, and debug component of VisualAge for COBOL Version 2 on OS/2. Installation details are covered as well as application development techniques. Several practical examples are provided on diskette for you to install on your host and use with the book. The redbook gives you an introduction to developing host applications from a workstation environment and explains in detail how to configure your workstation for communicating with the host via TCP/IP. You are led through the setup of the TCP/IP as well as of Network File System (NFS), the file system you need. The redbook describes how to configure your workstation for communicating with the host via APPC, the configuration of the Communications Manager/2 for using APPC and SMARTdata UTILITIES, and the changes you have to make on the workstation side as well as on the host side are explained. This redbook also covers the configuration of a WorkFrame project and the use of the project files by use of a sample program. In this sample, you learn step by step how to create a project and how to edit, compile, and debug the programs. A more complex project with DB2 access is shown also. You are also shown, by means of a sample, how to use VSAM for the workstation for local and remote data access, including customizing data description and conversion for transparent remote data access. Knowledge of application development in an MVS environm

This redbook details the configuration of a client/server environment consisting of the IBM COBOL, DB2, and CICS family of products on OS/2, AIX and MVS. Installation details as well as application development techniq ues are covered. The book was written for those interested in the interaction of the above family of products when the applications are written in COBOL. Technical marketing, application development, and local area networking personnel will find this information particularly useful. Several practical examples are used throughout the book on the various operating systems for illustration. Knowledge of COBOL programming, CICS, DB2, OS/2, and AIX is presumed. Application development knowledge in an MVS environment is a prerequisite for the MVS portions of the book.

This document introduces and illustrates the techniques needed to start exploiting the immense possibilities offered by the object-oriented capabilities of IBM's VisualAge for COBOL for OS/2 and related products in the IBM COBOL family of products. It introduces basic object-oriented concepts, describes in an illustrated manner how to code those concepts using IBM VisualAge for COBOL for OS/2, and provides a fictional account of how an application was written using an object-oriented approach with IBM VisualAge for COBOL for OS/2. This document was written for anyone expecting to be involved in the production of object-oriented COBOL programs and presumes knowledge of COBOL.
