About the technology
RPG on IBM i
RPG is a business programming language built for transaction-heavy applications on IBM i systems. It is commonly associated with IBM i, AS/400 and System i environments that run finance, manufacturing, logistics, retail and distribution operations. Modern RPG, especially RPG IV and free-form RPG, supports structured application logic while preserving direct access to established business data.
Core business systems
RPG applications handle order processing, inventory, purchasing, invoicing, production planning and customer records. They often sit at the center of operations, connecting users, batch jobs, databases and external services. Companies bring in specialists when these systems need reliable changes without disrupting daily transactions.
- Extend ERP and warehouse workflows
- Maintain order, stock and billing logic
- Add APIs and integrations to legacy applications
- Refactor fixed-format RPG into maintainable free-form code
Ecosystem and tools
Strong RPG work requires more than language knowledge. Specialists work with IBM i, Db2 for i, CL, SQL, job queues, subsystems, libraries and security controls. Depending on the environment, they also use ILE concepts, service programs, embedded SQL, APIs, web services and source-control workflows suited to IBM i delivery.
When expertise matters
Freelance expertise is useful when internal knowledge is limited, a key specialist is unavailable or a critical IBM i release must move forward. It can support migration planning, application modernization, integration projects and production support. In Germany, many companies need specialists who can collaborate remotely while coordinating clearly with local operations, vendors and business teams.
- Assess undocumented RPG and Db2 code
- Prepare IBM i upgrades or modernization steps
- Stabilize batch processing and interfaces
- Transfer knowledge to internal teams
What strong specialists deliver
Reliable professionals understand the business rules hidden inside long-running applications. They trace dependencies before changing code, test database updates and account for batch schedules, locking, authority and recovery procedures. They communicate risks in plain language and leave behind documentation that helps the next team maintain the system.
RPG and modern integration
RPG does not have to remain isolated from newer technology. Experts can expose selected business functions through REST or SOAP services, connect Db2 for i with external applications and support event or file-based integrations where appropriate. Good modernization preserves dependable transaction logic while improving access, observability and maintainability.
When evaluating a freelancer, ask for examples of comparable IBM i environments, RPG modernization work and production changes. Confirm their experience with the relevant release, database structure, deployment process and operational constraints. Practical knowledge of the surrounding system is often more valuable than familiarity with syntax alone.
Frequently asked questions
Key details about RPG, drawn from the questions we get asked most.
RPG is used to build and maintain transaction-processing applications on IBM i systems. Companies rely on it for orders, inventory, finance, manufacturing, logistics and other workflows that depend on consistent business rules and database access.
RPG is closely integrated with IBM i and Db2 for i, which can make it highly effective for established operational systems. Newer languages may offer broader web ecosystems, but replacing RPG is not automatically safer or cheaper when critical processes and data models already depend on it.
A strong RPG specialist often also knows IBM i administration concepts, Db2 for i, SQL, CL, ILE, job queues and system security. Experience with APIs, web services, source control and integration patterns is valuable when connecting established applications to modern systems.
The right level depends on the system and the risk of the change. RPG maintenance, production fixes and modernization require someone who can understand existing business rules, dependencies, data structures and operational procedures rather than only write new code.
Yes, many RPG tasks can be performed remotely with secure access, clear release procedures and reliable communication. On-site work may still help during workshops, production transitions or knowledge transfer, especially when German-speaking business teams and local operations are closely involved.
RPG in its modern form usually refers to RPG IV and free-form RPG within the ILE environment. It supports clearer structure, embedded SQL and service-oriented integration while continuing to run on IBM i and work with established applications.
Ask how the specialist approaches undocumented code, database changes, testing, deployment and rollback. A capable RPG professional can explain dependencies, batch behavior, authority settings and business impact in concrete terms, not just discuss syntax.
RPG is a programming language, while AS/400 is the former name of the IBM midrange system now known as IBM i. The terms are often used together because many AS/400 applications were written in RPG, but an IBM i environment can also include SQL, CL and other technologies.
