About the technology
RPG on IBM i
RPG is a business programming language closely associated with IBM i systems, formerly known as AS400 environments. Companies use it to run dependable core applications for order processing, inventory, finance, manufacturing and logistics. Modern RPG, including RPG IV and RPGLE, supports structured programs, free-form syntax and service-oriented integration.
Core applications
RPG specialists work on applications where stability, data accuracy and continuous operation matter. Typical deliverables include:
- Order, purchasing and warehouse workflows
- Financial and accounting functions
- Manufacturing and logistics processes
- Batch jobs, reports and operational screens
- Interfaces for web and mobile applications
Ecosystem and tooling
RPG work usually involves IBM i, Db2 for i and CL programming. Strong specialists understand IBM Navigator for i, IBM i Access, job queues, libraries, subsystems and authority management. They may also use SQL, REST APIs, JSON, XML, Git-based workflows and development tools such as RDi to connect established applications with newer services.
When companies need help
Companies bring in freelance RPG expertise during modernization, migration and application extension projects. A specialist can assess tightly coupled source code, improve SQL performance, replace manual workflows or expose existing logic through APIs. In Germany, this often means working with teams that must preserve critical IBM i processes while introducing cloud services or contemporary user interfaces.
What strong specialists deliver
Experienced RPG professionals read unfamiliar codebases carefully and protect business rules before changing them. They know how record-level access, commitment control, locking, data areas and batch processing affect production systems. The best specialists explain trade-offs clearly, test changes against real operational scenarios and leave maintainable documentation for internal teams.
Collaboration and quality
Remote delivery works well when access, release procedures and IBM i environments are prepared in advance. On-site collaboration can help when a project involves complex operational knowledge, legacy dependencies or close coordination with German-speaking business teams. When assessing an expert, review comparable IBM i work, ask how they approach risk and modernization, and check whether they can connect RPG knowledge with SQL, APIs and secure deployment practices.
Frequently asked questions
Key details about RPG, drawn from the questions we get asked most.
RPG is used to build and maintain transaction-heavy business applications on IBM i. It commonly supports finance, inventory, manufacturing, distribution, order management and logistics processes.
RPG is specialized for long-running IBM i business systems, while languages such as Java, C# and JavaScript are used across broader application environments. RPG can be the stronger choice when existing business rules, Db2 for i data and operational reliability are central to the project.
A strong RPG specialist often also works with IBM i administration concepts, Db2 for i, SQL and CL. REST APIs, JSON, XML, Git, automated testing and secure integration are valuable when extending established applications.
The right level depends on the system’s complexity, production risk and modernization goals. A small enhancement may need focused knowledge of a codebase, while a core-system migration calls for a professional who understands RPG, IBM i operations, data dependencies and release control.
Yes, RPG projects can often be delivered remotely when secure IBM i access, test environments and clear release processes are available. On-site work may still help with workshops, operational handovers or systems that cannot be accessed outside the company network.
Not always, but German can simplify requirements work with local business teams and documentation in Germany. The essential requirement is precise communication about business rules, production risks and IBM i changes; English is common in technical collaboration.
Ask for examples of comparable IBM i systems, modernization work and production-safe changes. A capable RPG professional can explain data dependencies, testing, rollback plans and the effect of changes on batch jobs and connected applications.
Yes, RPG specialists can refactor free-form code, improve SQL usage and expose business logic through REST APIs. They can also help introduce web interfaces, automated delivery practices or complementary services without discarding reliable core processes.
