Our iSeries customers are interested in practical solutions and recognize that RPG’s (including RPG ILE, RPG III, or RPG IV) tight integration into the iSeries operating system and databases, still provides the best tool for getting the job done. In addition, many third-party web development tools that are RPG-centric have validated RPG’s role as a viable component of web-based application development. As we have proven, new technology can successfully coexist with RPG and the iSeries.
As many AS400 developers and programmers already know, RPG IV is the preferred choice for development on the iSeries (AS400) platform and is the fourth generation of the RPG language. IBM has continued to dramatically enhance the RPG IV programming language over the last few years. Our IBM Certified RPG developers continue to increase their knowledge of the enhancements of both RPG III and RPG IV. Based on IBM’s Developers Roadmap, RPG IV is a stepping stone and needs to coexist in developing applications in Java and WebSphere.
Through our experience, it is obvious that an increasing number of our customers desire to upgrade their old or build their new applications in ILE. They have discovered that the time issue of repetitive programming in RPG/400 in numerous places is tedious but necessary. ILE is a technique for the modular development of applications, the main benefit being the ability to efficiently reuse code.
