3.7.28 List Tutorial Exercise 10

For the list ‘[a, b, c, d]’, the result is ‘((a = b) = c) = d’, which will compare ‘a’ and ‘b’ to produce a 1 or 0, which is then compared with ‘c’ to produce another 1 or 0, which is then compared with ‘d’. This is not at all what Joe wanted.

Here's a more correct method:

     1:  [7, 7, 7, 8, 7]      2:  [7, 7, 7, 8, 7]
         .                    1:  7
                                  .

       ' [7,7,7,8,7] <RET>          <RET> v r 1 <RET>

     1:  [1, 1, 1, 0, 1]      1:  0
         .                        .

         V M a =                  V R *
