Yes (I had to look it up to make sure as well!):

CP Language Reference Section 10.2:

--------------

  Receiver = "(" [VAR | IN] ident ":" ident ")".

--------------

It does make a difference as the following results in a compile-time error:

  PROCEDURE (IN box : Box) Salt, NEW;
    BEGIN
      box.k := 5
    END Salt;
