In the ever-evolving landscape of programming languages, one might stumble upon a less mainstream but highly specialized language known as RPG programming. RPG, which stands for Report Program Generator, is a high-level programming language primarily associated with IBM's AS/400 (now known as IBM i) platform. While it may not bask in the same limelight as widely recognized languages such as Java, Python, or C++, RPG programming quietly assumes a pivotal position within various sectors.

Within the confines of this blog, we shall embark on an exploration of the realm of RPG programming, elucidating its importance, and articulating the reasons why developers should ponder the adoption of this unique coding paradigm. We will also discuss whether RPG programming is still in use and what to look for when seeking skilled AS400 RPG programmers.

What is RPG Programming?

RPG programming, as the name suggests, was initially designed for generating reports on the IBM System/3 in the late 1960s. As time has elapsed, it has undergone a metamorphosis into a versatile coding language employed in the creation of applications for the IBM i platform, widely prevalent in sectors such as manufacturing, finance, logistics, and healthcare. RPG possesses a distinctive array of attributes, encompassing rigidly structured specifications, seamless integration with databases, and inherent functionalities, rendering it exceptionally suitable for corporate applications on IBM i frameworks

Why Should Developers Embrace RPG Programming?

Industry-specific Focus: AS400 RPG programming is tailored to address the needs of specific industries like manufacturing and finance. Developers working in these sectors can benefit from the language's native support for database operations, file handling, and business logic, making application development more efficient.

Legacy Systems: Many enterprises rely on legacy systems running on IBM i, making RPG programmers essential to maintain and enhance these systems. Embracing RPG programming can create numerous job opportunities for developers in this space.

Stability and Security: IBM i is known for its robust security features, and AS400 RPG programming helps maintain the security and stability of applications. Developers working with RPG can contribute to building and maintaining dependable and secure systems.

Is RPG Programming Still Used?

Yes, RPG programming is still widely used in many industries that rely on IBM i systems. While it may not be as trendy as some newer languages, RPG remains a fundamental component of legacy applications. This continued demand for RPG programmers means that learning and mastering RPG can be a valuable skill, offering job stability and opportunities for those willing to invest in it.

What to Look for in AS/400 RPG Programmers?

If you are considering hiring RPG programmers or becoming one yourself, here are some key qualities and skills to look for:

RPG Expertise: An in-depth understanding of RPG programming is a must. Knowledge of different RPG versions, such as RPG II, RPG III, RPG IV, and Free-Form RPG, is essential.

Database Skills: RPG programmers should be proficient in working with IBM's DB2 database system, which is tightly integrated with RPG applications.

Problem-Solving Abilities: AS400 RPG programmers often work on legacy systems with complex business logic. They need strong problem-solving skills to troubleshoot issues and enhance existing applications.

Communication: Effective communication skills are crucial for collaborating with other team members, business stakeholders, and end-users to understand and meet project requirements.

Adaptable: RPG programmers should be willing to adapt to changing technology landscapes and keep their skills up-to-date.

Looking for Skilled RPG Programmers?

If you are in need of skilled RPG programmers or aspire to become one, it's essential to connect with professionals who have expertise in this niche field. Look for job boards, online communities, and technical forums dedicated to AS/400 or IBM i programming. Additionally, consider collaborating with reputable staffing agencies and recruitment platforms specializing in IBM i and RPG programming to find the right talent or opportunities.


RPG programming, though not as mainstream as some other programming languages, remains an integral part of numerous industries that rely on IBM i systems. As legacy systems persist, RPG programmers continue to be in demand, offering job stability and career prospects. By embracing RPG programming and connecting with skilled AS400 RPG programmers, you can contribute to the maintenance, improvement, and security of critical business applications on the IBM i platform.
