Language Environment supports ILC between routines written in C/C++ and COBOL under CICS® as follows:
  • Calls supported as documented in the sections "Calling between C++ and COBOL" and "Calling between C and COBOL" with the exception that there is no support for ILC calls to or from routines written in pre-Language Environment-conforming versions of C or COBOL.
  • There is no support for ILC calls to or from routines written in pre-Language Environment-conforming versions of C or COBOL.

All components of your C/C++ to COBOL ILC application must be reentrant.

If there is any ILC with a run unit under CICS, each compile unit must be compiled with a Language Environment-conforming compiler.

For more information about ILC between C/C++ and COBOL, see Communicating between C and COBOL and "Communicating between C++ and COBOL" on page 53.
