PL/I for VSE

Maintain and optimize PL/I applications on IBM VSE systems

IBM® PL/I for VSE is a software development environment for optimizing PL/I applications on IBM VSE operating systems. Through integration with the IBM Language Environment®, the solution allows you to develop applications in multiple languages.

PL/I for VSE supports multiple-language development and use of reusable components to help you maintain and upgrade your applications with modern technologies.

Enhances programmer productivity with built-in functions and diagnostic tools.
Delivers interlanguage support through the Language Environment, which provides a common set of runtime libraries and callable services.
Provides application portability using powerful input/output facilities.

Enhances programmer productivity

Provides built-in functions for array processing, error handling, math computation, string-handling and more.
Enables production of modular programs with block-oriented reusable code.
Supplies defaults to reduce the number of declarations and other program statements.
Supports virtual storage constraint relief, allowing you to develop large applications and extensive tables of data without resorting to segmentation techniques.
Provides condition handling and diagnostic facilities to prevent programming errors.

Delivers interlanguage support

Uses common conventions, runtime facilities and callable services to provide a consistent application development environment.
Enables you to access library routines and include modules created by IBM COBOL for VSE.
Supports the functions of IBM PL/I for MVS™ & VM.
Supports reentrant interlanguage communication (ILC) applications.

Provides application portability

Provides input and output facilities, allowing you to take advantage of data files, access methods and other devices provided by the operating system.
Allows you to define input and output device types in runtime job control language (JCL), making your source programs device independent.
