RPG is a high-level programming language for business applications, introduced in 1959 for the IBM 1401. It is most well known as the primary programming language of IBM's midrange computer product line, including the IBM i operating system. [1] .

This chapter takes you through the steps to create and run an RPG IV program. It assumes you are using one of two ways to do your coding: If you are using RDi: Create a connection to your IBM i. Create a library. Remember the name of the library you create. You need it later when you call your first program.

2021年12月27日 · 在as400系统中，rpgle是核心的开发语言之一，广泛用于企业级应用，如财务、供应链管理和生产自动化等。 RPGLE 结合了过程式编程和声明式编程的特点，允许 开发 者混合使用传统的四象限编程模型和更现代的自由格式代码。

The first thing you should know in RPG IV (RPGLE) is, It is a positional language which means that we are allowed to write code at specific columns only.

This reference provides information about the RPG IV language as it is implemented using the ILE RPG compiler with the IBM i operating system. PDF file for ILE RPG Reference You can view and print a PDF file of this information. About ILE RPG Reference Read this section for information about the reference.

2013年8月28日 · RPG是OPM编程模式，即RPG编程的代码不能编译成*MODULE；编译只能直接生成一个程序，*PGM。 RPGLE是ILE编程模式。 OS/400环境下，ILE是集成开发环境。 在ILE环境下，所有加入ILE的计算机语言如RPG、C、C++、COBOLE等可以把各自的源代码编译成MODULE——一个中间代码形式，相当于DOS，或windows下编译C\C++，或者COBOLE，产生的.O的目标代码。 400环境下，生成modules后，再用CRTPGM把不同语言编译成的modules链 …

2020年4月19日 · Hello world RPGLE Tutorial takes you through the steps to create and run a RPG IV program. In this tutorial, I am going to show how to create a simple free format RPGLE program step by step using IBM Rational Developer and Program Development Manager in AS400 emulator which is commonly use as green screen or 5250 emulator.

2021年5月27日 · 本文档是一份AS/400程序员培训手册，详细介绍了RPGLE编程的基础，包括程序流程、D/F/C行的用法、入口参数、数据库交互、调试技巧和实用命令。 内容涵盖简单的程序编写、程序流程控制、D行和F行的声明与使用、C行的ILE操作码、数据库相关知识如LF和MEMBER、游标、事务处理、DEBUG调试方法，以及CL和CMD命令的使用。 此外，还讨论了屏幕文件、数组的使用、SQLRPGLE和SAVF的备份恢复等高级主题，旨在帮助读者全面掌握AS/400平台上 …

ILE RPG is an implementation of the RPG IV programming language in the Integrated Language Environment. It is one of the family of ILE compilers available on IBM i. ILE is an approach to programming on IBM i. It is the result of major enhancements to the IBM i machine architecture and the IBM i operating system.
