Thomas Snyder Written for experienced RPG programmers who want to take advantage of the latest technologiesa??such as Excel spreadsheets, Adobe files, and e-maila??from within their existing applications without buying costly software, this manual illustrates how to integrate RPG and Java in easy-to-understand code and with cost-effective options. Currently, there exists a very distinct line of expertise between IBM I programmers and Windows and Internet programmers, and this reference breaks through those obstacles to show common development tools for sharing information and building more compatible interfaces. Filling a very crucial gap, this resource shows programmers how to automatically e-mail reports using RPG and JavaMail, how to embed SQL and create text and XML files from within RPG, and how to migrate existing green-bar reports to Excel spreadsheets. An essential reference, this guide covers hard-to-find yet crucial information and introduces RPG programmers to modern environments.

4421 рубOpen Query File Magic!
Ted Holt OPNQRYF (Open Query File) is the most powerful, most complex, and least documented command in the CL language. You can use it to sort and summarize data, but it can also do much more for you. It allows you to create new fields and assign values to them, perform complex joins of multiple files, create new files with existing and calculated fields, select records (even based on summarized data), and much more! The more you learn about OPNQRYF, the more opportunities you will find to use it in your applications. This book explains the ins and outs of OPNQRYF from the basic operations through the most complex mapping and selection parameters. This new edition of the best-selling book includes invaluable new material. There are new chapters on date data type,ILE, and the Year 2000 issue. The book is reorganized to make it more useful not only as a learning tool, but also as a reference for on-going value.

John Bloomer A distributed application is designed to access resources across a network. In a broad sense, these resources could be user input, a central database, configuration files, etc., that are distributed on various computers across the network, rather than found on a single computer. RPC, or remote procedure calling, is the ability to distribute the execution of functions on remote computers outside of the application's current address space. This allows you to break large or complex programming problems intoroutines that can be executed independently of one another to take advantage of multiple computers. Thus, RPC makes it possible to attack a problem using a form of parallel or multiprocessing. Written from a programmer's perspective, this book shows what you can do with Sun RPC, the de facto standard on UNIX systems. It covers related programming topics for Sun and other UNIX systems and teaches through examples.

Richard Shaler, Robin Klima, Richard, Shaler Aimed at the experienced RPG programmer, this book will quickly take you from your RPG III skills to writing powerful RPG IV programs. It addresses the difference between RPG III and RPG IV so that you can quickly become a productive RPG IV programmer. This book contains extensive code examples that compare the two RPG languages and also introduces the ILE capabilities that can be used to your advantage. There are two new chapters on subprocedures: one that explains why the powerful new capabilities ofsubprocedures that let you break modules down into multiple procedures are so important, and another that shows you, by example, how to code the P-specs that make it all possible. They have added a chapter on conditional compiler objects to show you how the old directives have been enhanced, and what new directives are available. And finally, they have added a chapter on implementing object-oriented concepts in RPG. With the industry quickly moving towards OO programming, it is...
