Mixed Language Programming

This section covers parameters, return codes and call conventions for mixed language development with native COBOL.

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.
