Case is ignored for all command keywords.
Keywords can be shortened to any unambiguous form. For instance, load rules, load rul, load r, and loa r are all acceptable. Typing just l is ambiguous for the commands load , log , and list . However, because load is such a frequently used command, it takes special precedence over the other commands beginning with l , which means that typing just l will execute only the load command. To get information on what these commands do, type help .
