This section gives you a high-level overview of ILC considerations for existing OS/VS COBOL programs. For exact details and for the latest information on ILC under Language Environment, see the Language Environment Writing Interlanguage Applications.
For CICS, you can continue to use EXEC CICS LINK and EXEC CICS XCTL to communicate with other languages.
Table 1 shows the action required for applications with existing ILC:
| High-level language | Comments |
|---|---|
| PL/I | OS/VS COBOL programs that call or are called by PL/I must be upgraded. |
| FORTRAN | OS/VS COBOL programs that call or are called by FORTRAN must be upgraded. |
| C | ILC between OS/VS COBOL programs and C programs is not, and has never been, supported. |
