**************
Locations View
**************
From `View`, click on the blue link: `stack.ads:32`, this will open the file
:file:`stack.ads` at line 32. Then from the source editor (file
:file:`stack.ads`), select the contextual menu `References->Find all references
to View`: this highlights the `Locations` tree which now contains all the
references for `View`, grouped by files (:file:`stack.ads` and
:file:`stack.adb`).
The first location is highlighted automatically: this is the spec of the
procedure `View`. Now click in the tree on the `+` sign (or triangle) at the
left of :file:`stack.adb`: two locations are listed, at line 90 and 97. Click
on each of these locations: they correspond to the procedure body.
The `Find all references` capability is another way to list all the uses of an
entity, and it confirms that `View` isn't called in our project.
Remove *View* body by e.g selecting it, and pressing the :kbd:`Delete` key,
then save the file (:kbd:`Ctrl-S`).
Do the same for the spec, save the file.
Close the :file:`stack.ads` and :file:`stack.adb` files (menu File->Close, or
using the shortcut :kbd:`Ctrl-W`). Rebuild by pressing the :kbd:`F4` key.
Let's now see how to create a project corresponding to the *sdc*
project we've used in this tutorial.
