I saw an implementation of boxes that looks like this: (define box (lambda (x) (cons x #f))) (define unbox (lambda (x) (car x))) (define set-box! (lambda (x v) (set-car! x v))) Is the point akin to a pointer in C? ie, so you could have args that "changed" (call by variable)? Is this an OK defn of boxes? -- Jason Coughlin ( jk0@sun.soe.clarkson.edu , jk0@clutx ) "Every jumbled pile of person has a thinking part that wonders what the part that isn't thinking isn't thinking of." - They Might Be Giants
