Chapter 24: PL/I Extension

24.1 Introduction

The Revolve PL/I Extension™ gives you the ability to apply the powerful application inventory, analysis, and maintenance capabilities of Micro Focus Revolve to your enterprise PL/I systems. It extends Revolve's analysis and implementation features for use by PL/I programmers.

The PL/I Extension introduces a PL/I language parser that identifies individual components of an application system (such as programs and associated include files, variables, literals, job steps, screens, data files and databases) and adds them to the Revolve project database.

Revolve enables programmers to visualize details of the application project, determine where changes must be implemented, automatically trace the impact of those changes across the entire application project, and document and guide the change process.

24.3 Technical Information

The PL/I Extension is a separately install-able component for Revolve. It shares the same operating system and microprocessor requirements as Revolve. An additional 2 Mb free hard disk space is needed to load all corresponding files.
