CICS® translator support for pre-Language Environment compilers is withdrawn. Runtime support is provided for existing application programs that were developed using these compilers, except for OS/VS COBOL and OO COBOL programs, which do not have runtime support.
Withdrawal of support for pre-Language Environment compilers
- OS/VS COBOL (5740-CB1, 5740-LM1, and 5734-CB4)
- VS COBOL II (5668-958 and 5688-023)
- OS PL/I Version 1 (5734-PL1)
- OS PL/I Version 2 (5668-910 and 5668-909)
- SAA AD/Cycle C/370™ (5688-216)
For details of the compilers that are supported by CICS, see High-level language support.
- COBOL
- The DFHEITVL, DFHEXTVL, DFHEBTVL, DFHEITCL, and DFHEXTCL procedures.
- PL/I
- The DFHEITPL, DFHEXTPL, and DFHEBTPL procedures.
- C
- The DFHEITDL and DFHEXTDL procedures.

Runtime support for programs developed using pre-Language Environment compilers
Although application program development support for obsolete compilers is withdrawn, CICS usually continues to provide runtime support for your existing application programs that were developed using these old compilers. However, to apply maintenance to these application programs, use one of the supported compilers that conforms to Language Environment.
Applications
compiled and linked with pre-Language Environment compilers usually
run successfully using the runtime support provided by Language Environment. These
applications do not usually need to be recompiled or re-link-edited.
If required, adjust Language
Environment runtime options to allow these applications to run
correctly. For more information, see the 
z/OS Language Environment Run-Time Application
Migration Guide and
the migration information for the language in use. Because pre-Language
Environment compilers are not Language Environment-conforming, programs
compiled by these compilers cannot take advantage of all Language Environment facilities
in a CICS region.
Runtime libraries provided by Language Environment replace the runtime libraries that were provided with older compilers such as VS COBOL II, OS PL/I, and C/370. The runtime libraries provided with pre-Language Environment compilers are not supported. Language libraries, other than the Language Environment libraries, must not be present in your CICS startup JCL.
Withdrawal of runtime support for OO COBOL
In this CICS release, you cannot use COBOL class definitions and methods (object-oriented COBOL). This restriction includes both Java™ classes and COBOL classes.
Modules using OO features and compiled in earlier CICS releases with the OOCOBOL translator option cannot run in this CICS release. The OOCOBOL translator option was used for the older SOM-based (System Object Manager-based) OO COBOL, and runtime support for this form of OO COBOL was withdrawn in z/OS® V1.2. The newer Java-based OO COBOL, which is used in Enterprise COBOL, is not supported by the CICS translator.
