Language Environment support for PL/I

Language Environment® is a prerequisite for application programs compiled using the IBM® Enterprise PL/I for z/OS® compiler. Language Environment incorporates the runtime libraries required for PL/I compilers.

PL/I support is also required if you use the web services support in CICS®; in particular, it is required if you use the supplied SOAP 1.1 and SOAP 1.2 message handler programs.

To run CICS PL/I application programs:

Install support for Language Environment, ensuring that CICS can initialize the Language Environment environment during startup.
Install resource definitions for the programs with the LANGUAGE attribute specified as LANGUAGE(PLI) or leave blank.

For information about Language Environment, see z/OS Language Environment Customization. For information about installing program resource definitions, see Resource definition installation.
