But why would 207 be looking for teachpacks in the 206 install directory and what can I do to rectify this situation? <pre class="moz-signature" cols="80">-- (let recur ((lis x) (k k)) (if (zero? k) (values '() lis) (receive (prefix suffix) (recur (cdr lis) (- k 1)) (values (cons (car lis) prefix) suffix))))) </pre> </body> </html>
