ILC Applications

Language Environment does not support the OS PL/I-COBOL ILC applications. You must relink any OS PL/I object module in a PL/I-COBOL ILC application. See Differences in Interlanguage Communication Support for ILC support under Language Environment. If you relink your OS PL/I object module in the PL/I-COBOL ILC application with PN69803, however, the resultant load module is supported by Language Environment. PN69803 provides you the flexibility to prepare the PL/I-COBOL ILC relinking while you are using OS PL/I Version 2 Release 3. When you complete the relinking, you can switch to Language Environment whenever you are ready.

Before you relink your PL/I-COBOL ILC applications with PN69803, you must first apply the following PL/I-COBOL ILC APARs to PL/I and COBOL:

Note:
VS COBOL II V1R4.0 has the above COBOL APARs in its base code.

If you have not applied the above APARs, PN69803 will not work. The above APARs are not required if your applications do not contain PL/I-COBOL ILC.

Even though your PL/I-COBOL ILC applications are relinked with PN69803, you might still be required to link them with Language Environment if they contain a function described in this book or in COBOL for OS/390 & VM Migration Guide that requires relinking. For example, you will still have to relink your application if it contains any COBOL NORES or the load module contains an OS PL/I object module that is not supported by Language Environment. In the latter case, you must recompile your OS PL/I object module with Enterprise PL/I or OS PL/I Version 2.
