Display compile or verify error messages inline or as annotations

Compile or verify error messages from the error list view can be displayed inline in the editor or as annotations in the margin column of the editor.

About this task

Inline style
When displayed inline, error messages display one message per line. For example, the following image shows four error messages for the selected line:

Annotation style (default)
With annotations, error messages are displayed as annotation icons in the margin column as in the following image. Annotations present a less cluttered view of the editor while still allowing access to the message information:

  3. Compile or verify your source.

    Right-click your source member in the remote systems view or in the i Project view and select a Compile or a Verify option. The following example uses Compile.


    After you compile, the errors will be shown inline or as annotations depending on the message style that you have chosen. The errors will also be listed in the Error List view.

    Messages after compile

    • If you compile without the source open in the editor, you can double-click a message in the Error List view to open the editor and have the messages inserted.
    • If you compile from the i Projects view by right-clicking a member, selecting Remote Actions and choosing one of the compile options, the errors will not be loaded automatically. In this case, to see the errors, in the Job Status view, right-click the job and select Task Actions > Retrieve Errors.
