7.6.  Transition Routines

     ADL has an	internal structure known as  the  Transition
Vector.	 This structure	is a list of ten verb IDs and is set
and used by the	following routines.  These routines are	typ-
ically	used in	the ACTION routines of rooms in	scenarios in
order to move the player around.

$setv	( $setv	verb1 verb2 verb3 ... verb10 ) -> No  return
	value.	 Initializes  the  Transition  Vector to the
	list of	verbs verb1 verb2 verb3	... verb10.

	Example:
		     ($setv north south	east west ne se	nw sw up down)



$hit	( $hit obj loc1	loc2 loc3 ... loc10 ) ->  No  return
	value.	Scans the Transition Vector for	a match	with
	the current Verb.  If found, obj  is  moved  to	 the
	corresponding  loc.   Nothing happens if no match is
	found.	An attempt to move an object to	 location  0
	(.ALL) is ignored.

	Example:
		     room1(ACTION) =
			     ($hit .ME room2 room3 room4 0 0 0 0 0 0 0)
		     ;



$miss	( $miss	rout1 rout2 rout3 ... rout10 ) -> No  return
	value.	Scans the Transition Vector for	a match	with
	the current Verb.  If found, the corresponding	rout
	is  called.   Nothing  happens if no match is found.
	An attempt to call routine 0 does nothing.

	Example:
		     cg	= ($say	"You can't go that way.n")

		     room2(ACTION) =
			     ($miss 0 0	0 cg cg	cg cg cg cg cg)
		     ;
