Mixed Language Programming with Native COBOL

This section covers parameters, return codes and call conventions for mixed language development with native COBOL.
Restriction: The following applies to native COBOL only.

Applications can contain programs written in both COBOL and other languages, such as C. COBOL programs call non-COBOL programs using the standard COBOL CALL ... USING statement.

Although you pass parameters to non-COBOL programs in broadly the same way as to COBOL programs, the interfaces to programs in different languages differ from each other and they need to correspond.
