   I recieved quite a few answers to my apl quiz. Here are
some of the answers. The overwhelming reply was something
of the form:

     (iota 0) rho vector

(I was quite pleased to see that the null vector was
produced in a variety of ways; (iota 0), '' ,(0 rho 0).

The generalization of the previous answer is:

     ((1 ne rho vector)/ rho vector) rho vector

  Of course, as some of you pointed out, the structure
of the result can be radically different.

   Other ways for the specialized case were:

      vector[1]

      1 take vector

Thanks one and all who answered.
