Mapping of List data types.

CPN specification	B Notation
ins new 1 x if x is not a number of list 1, then x is inserted at the end of 1, otherwise 1 is returned	ann <– ins new(ll,xx) = = if xx: ran(ll) then aa: = ll else aa: = ll < -xx end
nil or [] empty list	[]
hd lst head, the first element of the list	first(lst)
tl lst tail, the last element of the list	tail(lst)
Length lst length of list	size(lst)
elt:: List prepend element as head of list	elt - > lst
Rev lst reverse list	rev(lst)
Rev lst reverse list	lst(nth)
list.take(lst,n) returns first n elements of list	Lst/|\n
list.drop(lst,n) returns what is left after dropping first n elements of list	lst\|/n
list.null lst returns true if element is empty	(lst = [])
mem.null lst returns true if element is in the list	elt:ran(lst)
Contains lst1 lst2 returns true if all elements in list 2 are elements in list 1 (ignoring the multiplicity of elements in list 2)	ran(lst1)<:ran(lst2)
union lst1 lst2 (or lst1^∧lst2 the concatenation of two list	lst1^∧lst2
Ins lst elt inserts element at the end of list	lst < -elt
