Using a dialog Menu to prompt for validation
The MENU statement has an optional STYLE attribute
        that can be set to 'dialog', automatically opening a temporary modal window. You can also
        define a message and icon with the COMMENT and IMAGE
        attributes. This provides a simple way to prompt the user to confirm some action or
        operation that has been selected.
The menu options appear as buttons at the bottom of the window. Unlike standard menus, the dialog
            menu is automatically exited after any action clause such as ON
                ACTION, COMMAND or ON IDLE. You do not
            need an EXIT MENU statement.
