IBM Z Open Editor banner

We are excited to announce that IBM Z Open Editor is now available as a FREE, easily downloadable extension in Visual Studio Code’s marketplace.

IBM Z Open Editor is perfect for developers interested in mainframe application development, especially those who prefer a modern development environment. By bringing IBM z/OS language support to one of today’s most popular integrated development environments (IDE), Visual Studio Code (VS Code), IBM Z Open Editor gives developers the freedom to code in COBOL and PL/I using the same editor they can use for languages such as Java and JavaScript.

The difference is more than aesthetic: IBM Z Open Editor is backed by IBM’s powerful language server protocol (LSP) for COBOL and PL/I. It can handle embedded statements for CICS, IMS, and DB2, and also support Job Control Language (JCL) syntax highlighting. For COBOL and PL/I, in addition to syntax highlighting, the LSP support means that our extension can also perform modern editing functions such as:

  • Code completion: When you start typing a command, variable, or paragraph name, a selection list of commands, defined variable names, and code snippets is displayed automatically.

  • Copybook/Include resolution: To preview the contents of a copybook, move your mouse cursor over the copybook name in a COPY statement. You can also open the copybook in a separate editor by pressing Ctrl+Click (Windows) or Cmd+Click (Mac). Resolving PL/I include files works similarly.

  • Peek References: A Results References view is displayed underneath the variable or paragraph. Click any result to go to that location in the file.

  • Outline View: Explore and navigate your COBOL and PL/I code efficiently with a complete sortable and interactive table of contents for your code. Use the Outline View to quickly jump to any part of your code by clicking its section header, or search for identifiers within the outline. Icons next to each Outline View item make it easy to identify procedures, loops, and more.

  • Integrations to make life easier
    • Git: Quickly find and access recently edited code
      Colored bars highlight recently changed lines in an open editor window, while clicking on the SCM (Git) view will reveal and provide access to files that have been recently modified. If you have the GitLens extension, you can also view in-editor annotations to see the most recent commit modifying each line of code.
    • Zowe: Interact directly with your mainframe
      IBM Z Open Editor is designed to integrate seamlessly with the Visual Studio Code Extension for Zowe. The Visual Studio Code Extension for Zowe allows you to connect remotely to the IBM z/OS mainframe system, where you can manage your data sets, files, and jobs, and use IBM Z Open Editor to efficiently and effectively edit your COBOL and PL/I applications.

What’s next?

IBM Z Open Editor follows Wazi, a technical preview that explored integrating mainframe application development capabilities into modern development environments and pipelines. Based on Wazi’s success and user feedback, we made some of Wazi’s capabilities available in IBM Z Open Editor. If you tried out Wazi while it was live, thank you! Your support and feedback is invaluable for improving IBM Z Open Editor.
