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:
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.
