COBOL
A long-established business programming language still running production logic on IBM i and other legacy enterprise platforms alongside RPG.
COBOL remains present in many IBM i shops, particularly those that migrated from other legacy platforms or maintain long-running financial and business logic. AI-assisted modernization tooling for IBM i is more heavily focused on RPG than COBOL, so IBM i shops with significant COBOL should confirm vendor tool coverage before assuming feature parity with RPG-focused tools.
