Imagine you’re trying to quickly diagnose an abended job. You could open up a 3270 and do lots of typing. Or you could use a rich client like IBM Developer for z/OS. In the Remote Systems view you can find your job under the JES subsystem. From there you’re a double-click away from a richer, more integrated, job detective experience.

You can open an individual job spool or a combined view. Up until a couple years ago, you’d have to use a plain text editor, not unlike what you’d see in SDSF. Then the JES Spool Editor was unveiled, providing syntax coloring, the ability to link to host resources along with some IBM Knowledge Center integration.

Still seeing the z Systems LPEX Editor when viewing spools? Go to the File Associations preference page to change the default “spool” editor.

JES Spool Editor Outline view

If you work with large job spools, chances are you do a fair bit of scrolling to find what you’re looking for. But as of IDz 14.2.2 and other products in the Aqua stack, you can get around more easily. Take advantage of the new outline view for the JES Spool Editor!

As with the COBOL, JCL and other Eclipse editors, the accompanying outline provides a structured way to view and navigate content. The JES Spool Editor outline view lets you quickly move across data sets. By expanding a top-level node, you can go deeper. You can navigate through JCL or examine messages. Like other outline views, editor cursor position and outline view selection stay in sync so you always get a sense of where you’re at.

Besides faster and more fluid navigation, the outline view helps you decipher messages. Upon seeing an unfamiliar one, your instinct might be to begrudgingly flip through a manual or bring up your browser for a Google search. With the outline view, give your fingers a rest. Use the context menu to search the Knowledge Center and have results presented to you in your favorite browser.


Sometimes subtle improvements, like fewer keystrokes, less scrolling and structured visualization, elevate user experiences to a new level. The new outline view for the JES Spool Editor seeks to do that and more.

  1. Thank you for that. It it several years ago I asked for something like this.
    But I was a bit more creative and think you should make it even better.

    When you have a “printed list” or right-click a top node you can’t do anything. Messages you can right-click and get a “Search Knowledge base” and that is fine.
    But let’s say I want to send a list from a job to someone else?
    What about an Export to -> Email, Excel, Text, CVS – that would be cool to.

    I am sure there must be other features people can think of – we are very creative and just want IDz to get better and better. You are doing a great job in that matter. IDz 14.2 compared to our start at 7.6 is two different worlds….

      Thank you for your constructive feedback, Peter. Yes, there are a lot of opportunities to expand on this functionality and you have some very good ideas. Feel free to open RFEs for enhancements you’d like to see in this area.
