RPG DEVELOPMENT AND MAINTENANCE

RPG Development and Maintenance for Business-Critical Systems

Wild Impala Enterprises supports RPG applications that still carry important business processes, from code analysis and enhancements to controlled production maintenance.

RPG enhancements Legacy analysis Production support
Support Scope

Keep core RPG applications reliable while change keeps moving.

For many organisations, RPG maintenance is not just bug fixing. It is the day-to-day discipline of protecting production behaviour while business rules, reports, integrations, and platform needs evolve.

DEV

RPG program development

Build and adjust RPG functionality around current business requirements, existing file structures, and the constraints of live systems.

ANALYSIS

Legacy code analysis

Trace inherited business logic, dependencies, risky procedures, and areas where code needs remediation before larger change.

SUPPORT

Production support

Support operational RPG applications with a focus on stability, controlled fixes, and careful handling of business-critical routines.

CHANGE

Enhancements and reliability improvements

Deliver targeted improvements that make applications clearer, more resilient, and easier to maintain over time.

Maintenance Method

Controlled support for systems that cannot afford casual change.

Wild Impala's support work is suited to legacy environments where production stability, business continuity, and code knowledge all matter.

  • Understand the business rule before changing the program.
  • Keep fixes traceable and aligned with client requirements.
  • Use maintenance findings to identify modernisation opportunities.
  • Support stable delivery for IBM i / AS400 applications that remain in use.
When To Engage

Useful when the RPG system is still important, but knowledge is thin.

Existing programs need enhancement

Business teams need new outputs, logic changes, or operational fixes without destabilising the wider system.

Code needs analysis before migration

Migration and platform work is easier when teams understand which RPG programs carry the important rules.

Maintenance should inform modernisation

Patterns found during support can feed a practical roadmap for RPGLE conversion and clearer service-based structures.

Related Services

Support can be paired with modernisation and migration planning.

Legacy RPG modernisation

Use support insights to move fixed-format or hard-to-maintain programs toward RPGLE and clearer structures.

FAQ

RPG support questions

What RPG development work does Wild Impala handle?

Wild Impala handles RPG program development, enhancements, legacy code analysis, controlled maintenance, and production support for business-critical applications.

Can Wild Impala work with existing production RPG systems?

Yes. The service is aimed at mature RPG and IBM i / AS400 systems where change needs to be careful, traceable, and aligned with business rules.

How does maintenance connect to modernisation?

Maintenance work often reveals duplicated logic, risky dependencies, and reliability issues that can feed a controlled modernisation roadmap.
