In the MOO, there a 2 basic sorts of verbs:(a) command verbs and (b) methods (callable verbs on objects).
(a) When a command is entered by a user, the server tries to (1) parse the line received and (2) to find a command verb that can execute it. This is discussed in section 10.4.1. See also: Chapter 2 in the MOO Programming Manuel for important information on ``built-in'' variables.
(b) Verbs can call other verbs that are executable (
Usually, those verbs use ``this none this'' for the dobj prep iobj
arguments. ``This none this'' is used to indicate non-command verbs,
since the parser can't possibly interpret a command as "this none
this". For these verbs, the permissions default to "rxd"; the "x" bit
is set so that they can be called from other programs. Read section
10.4.2 for more details on verb specification.
