Screen to RPC conversion

Convert Mainframe screen COBOL into RPC-style programs that preserve business rules—ready to expose as Hub APIs and modern services.

OL Code converts screen-driven Mainframe COBOL into RPC-style COBOL services. Conversion removes UI-specific logic while preserving business rules, producing a clean, stateless program that teams can expose through OpenLegacy Hub as APIs and modern channel services—without a full rewrite of the screen application.
