PL/I on z/OS

Application programming on z/OS

Programming Language/I (PL/I, pronounced "P-L one"), is a full-function, general-purpose, high-level programming language.

PL/I is suitable for the development of:

  • Commercial applications
  • Engineering/scientific applications
  • Many other applications

The process of compiling a PL/I source program and then link-editing the object deck into a load module is basically the same as it is for COBOL.

The relationship between JCL and program files is the same for PL/I as it is for COBOL and other HLLs.

  • PL/I program structure
  • Preprocessors
    The PL/I compiler allows you to select one or more of the integrated preprocessors as required for use in your program. You can select the include preprocessor, the macro preprocessor, the SQL preprocessor, or the CICS® preprocessor—and you can select the order in which you would like them to be called.
  • The SAX parser
    The PL/I compiler provides an interface called PLISAXx (x = A or B) that provides you with basic XML capability. The support includes a high-speed XML parser, which allows programs to accept inbound XML messages, check them for being well-formed, and transform their contents to PL/I data structures.
  • More information about the PL/I language
    The PL/I compiler is designed according to the specifications of industry standards as understood and interpreted by IBM® as of December 1987.
