### Conventions

Following are examples of the typographical and graphic conventions used in this guide:

- `Functions`, `utility program names`, `standard names`, and `classes`.
- ‘`Option flags`’
- `File Names`, `button names`, and `field names`.
- Variables.
- Emphasis.
- [optional information or parameters]
- Examples are described by text

                and then shown this way.

Commands that are entered by the user are preceded in this manual by the characters “`$` ” (dollar sign followed by space). If your system uses this sequence as a prompt, then the commands will appear exactly as you see them in the manual. If your system uses some other prompt, then the command will appear with the `$` replaced by whatever prompt you are using.

Full file names are shown with the “`/`” character as the directory separator; e.g., `parent-dir/subdir/myfile.adb`. If you are using GNAT on a Windows platform, please note that the “`\`” character should be used instead.
