Code a continuation that does nothing

continuations, r6rs, scheme

Solution

The most straightforward way is to use a simple "return" style continuation:

(call/cc (lambda (return) 
    (display 1) 
    ...
    (return) 
    (display "A")))

Does that help at all?

Problem

Maybe my question has a really simple answer, but I cannot find it. In Scheme R6RS how can I built a continuation that does nothing and requires any arguments? My goal is to have a continuation, let's name it `QUIT` such that if I have the following code: ``` ((lambda () (display 1) (display 2) (QUIT) (displey "A"))) ``` it preints 1 and 2 but not "A".+ Can you help me? Thank you.
