Native COBOL compared with managed COBOL Native COBOL and managed COBOL differ in how they compile and how the run-time management services, such as security, threading
and memory management are provided.

In addition, managed code in languages other than COBOL and native COBOL can interoperate by going through managed COBOL code.
