IBM Enterprise PL/I for z/OS is IBM's strategic PL/I compiler for the zSeries platform. Enterprise PL/I is comprised of features from OS PL/I, PL/I for MVS & VM, and VisualAge PL/I with additional features such as Unicode support, XML parsing capabilities, improved C and Java interoperability, integrated CICS preprocessor, and integrated SQL preprocessor.
Language Environment provides a single language run-time environment for COBOL, PL/I, C, and FORTRAN. In addition to support for existing applications, Language Environment also provides common condition handling, improved interlanguage communication (ILC), reusable libraries, and more efficient application development of interlanguage applications. Application development is simplified by the use of common conventions, common run-time facilities, and a set of shared callable services. Language Environment is required to run Enterprise PL/I programs.
Debug Tool provides significantly improved debugging function over previous PL/I debugging tools, and you can use it to debug Enterprise PL/I programs and other Language Environment-conforming language programs including COBOL and C/C++.
Debug Tool is included with the full-function version of the compiler.
