call-with-current-continuation
     
         (call/cc) A {Lisp} control function that
        takes a function f as its argument and calls f, passing it the
        current {continuation}, which is itself a function, k.  k,
        which represents the context of the call to call/cc, takes the
        result of call/cc (which is the result of f) and returns the
        final result of the whole program.  Thus if, for example, the
        final result is to print the value returned by call/cc then
        anything passed to k will also be printed.
     
        E.g, in {Scheme}:
     
         (define (f k)
        	 (k 1)
        	 (k 2)
        	 3)
     
         (display (call-with-current-continuation f))
     
        Will display 1.
