My point is for a non-trivial verb, how can I cram this in one DD line.

That is the same as:

4 : 0
la =. x >. y
sm =. x <. y
la - sm
)

We can substitute the intermediate variables:

4 : 0
(x >. y) - (x <. y)
)

And collapse onto one line: 4 : '(x >. y) - (x <. y)'

Worth noting is that we can write this as a fork: >. - <.

  -E
