High-level language support

Prerequisite: Language Environment run time

All programs compiled by a high-level language, whether by a Language Environment®-conforming compiler or not, must be run under CICS-Language Environment support.

Language Environment is a base element of z/OS® and provides the common runtime environment for COBOL, PL/I, C, and C++. For more information about how CICS uses the services of Language Environment, see Programming languages and Language Environment.

Pre-Language Environment compilers provided native runtime libraries for programming languages, but the native runtime libraries are not supported in CICS Transaction Server for z/OS, Version 5 Release 4. However, Language Environment provides object and load module compatibility for applications that are generated with certain pre-Language Environment compilers. Load modules that are created with these compilers, and link-edited with their associated runtime libraries, are compatible with the Language Environment without relinking. Also, object modules created with these compilers can be linked and run with Language Environment without recompiling.

CICS support for high-level languages

For details about CICS support for a specific high-level language and for changes in the CICS support after the CICS Transaction Server for z/OS, Version 5 Release 4 information is released, refer to the language and compiler documentation.

For information about the availability and end of service dates for IBM® products, see Software lifecycle information in IBM Support.

The following tables provide an overview of the releases of high-level languages and compilers that CICS Transaction Server for z/OS, Version 5 Release 4 supports.

Support for compilers and high-level language versions withdrawn from service

Periodically, assemblers, compilers, and high-level language versions are withdrawn from service. This can happen within the supported lifetime of a CICS release. Although continued compatibility is not necessarily affected within CICS at this point, it is strongly recommended that you upgrade the level of your environments to use the in-service equivalents of such unsupported assemblers, compilers, or high-level language versions before their end of service dates. IBM does not guarantee that such unsupported environments will remain useable within the CICS release after this point.
