intersect example in "Introduction to newLISP"

[fred]

@Cormullion:

From then "Introduction to newLISP" i think the difference function should be intersect in this example?



The intersect function finds the elements that are in both lists.



(difference d2 d1)

;-> ("." ".." ".DS_Store" "Language Modules" "Menu Scripts" "Plug-Ins" "Read Me.txt" "Scripts" "Unix Support")
