IMS COBOL / MFS migration

Convert IMS DC COBOL programs with MFS maps into runnable legacy code on the JVM you can play and validate in OL Next—MFS map conversations, not 3270.

OL Next converts IMS DC COBOL programs that use MFS maps into runnable legacy code on the JVM through the cobol-ims kit. Conversational flows keep SPA state across turns; embedded DB2 and DL/I segment calls can run against an H2 sandbox, a live host store, or a modern DB after data migration. Teams convert, play, and equivalence-test IMS applications in the web console or CLI. Legacy teams keep editing the COBOL in OL Next; the program runs off the host. Play multi-step MFS map conversations (not 3270).
