Administer
Effortless control over libraries, objects, restores and environments. Smart automation, automatic handling, and one-click fixes so you spend way less time babysitting the system.
Tune
Quickly spot and fix performance bottlenecks across your databases, jobs, memory and SQL. No more guessing, you get clear analyzers and optimization tools.
Program
Your coding life gets a serious upgrade. Modern RPG and CL productivity aids, advanced debugging, code quality checks and ready-made templates mean you write cleaner, faster code with fewer errors.
Modernise
Refactoring tools, API wizards, SQL conversion helpers and web enablement features that let you gradually turn legacy code into modern, maintainable applications without the big-bang risk.

What They Say

The one-click library clone and cross-reference fixer in PROJEX/4i saves me 2–3 hours every time I build a test environment. It fills the exact gaps that RSTLIB and manual recompiles always left behind!
