Hi Ric,
Sorry to send you a third response before you have had time to reply to
the first, but your emails have been so helpful and thought provoking.
(M1 D M2) y is equivalent to the formula D(M1(y), M2(y))
**Identified by a right argument only**
x (D1 D2 D3) y is equivalent to the formula D2(D1(x,y), D3(x,y))
**Identified by both a right and a left argument**
How do you write the equivalent of D2(D1(x,y), M(y)) in J?
Don
