Remove item from list

I'm trying to remove some items which both in two lists.
But the remove command doesn't work.

A='(0 1 2 3 4 5 6 7 8 9)
B='(1 3 5 7 9)
C=nil
foreach(item A
             if(member(item B) then
                C=remove(item A)
               )
            )

why the result is C= (0 1 2 3 4 5 6 7 8) not (0 2 4 6 8)?
how the remove works?

Who can help to tell me the reason or share me a right code to make it true~~
Thanks.

Hi Leon,

remove is a destructive function so you were correct to use copy.
Another (faster) method is to use cons, to create a new list, or the slowish following method
C = setof(item, A, !member(item, B))

Cheers, Dave
