2. Running GNAT SAS

Select the menu GNATSAS ‣ Analyze All in the menu bar at the top. This will run GNAT SAS, which first generates SCIL files, then runs the GNAT SAS analysis engines, and finally displays a summary of the problems found in the GNAT SAS Report Window.

Here, GNAT SAS reports a few medium and low messages.

Notice the different kinds of filters that are available on the right side of the window. Clicking on each of these filters will show/hide the corresponding messages in the Locations View at the bottom.

Uncheck the box medium in Message ranking. This clears the location view.

Check the box low in Message ranking. The location view now reports the low messages only.

Undo these changes to recover medium messages only. During all these changes, the GNAT SAS Report Window was not affected as it reports all problems found. The filters only apply to the Locations View.
