General facts about C++ to Fortran ILC
- A load module consisting of object code compiled with any Fortran compiler link-edited with object code compiled in another language is not reentrant, regardless of whether the Fortran routine was compiled with the RENT compiler option.
- Return codes cannot be passed from a C++ routine to the Fortran routine that invoked it.
- Fortran routines cannot operate under CICS®.
- Support for Fortran on VM is not provided by Language Environment.
- Several C++ and Fortran library routines have identical names; you will need to resolve name conflicts before link-editing your C++ to Fortran applications. See z/OS Language Environment Programming Guide for link-editing information.
- C++ is supported on MVS™ only.
- Fortran routines cannot operate in an XPLINK environment, so ILC with C routines compiled XPLINK is not supported.
- There is no ILC support between AMODE 31 and AMODE 64 applications. Fortran does not support AMODE 64.
