This is (also) the only one I could think of, but apparently there is no other
separator available in DD.
Thanks.

Are you looking for this?
PosDiff=: {{la-sm[sm=.x<.y[la=.x>.y}}

Again, I know all that, since quite long actually.
But now with the direct definition, {{ }} , how is it done there?

My point is for a non-trivial verb, how can I cram this in one DD line.
One way is to perform the definitions in-line:
4 : 'la - sm [ la =. x >. y [ sm =. x <. y'
There is also Michal Wallace's proposal to use '..' as a sentence separator,
with which you might write:
4 : 'la =. x >. y .. sm =. x <. y .. la - sm'
-E

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: >. - <.

PosDiff =: 4 : ('la =. x >. y' ; 'sm =. x <. y' ; 'la - sm')
How do I transfer this in a single line direct definition?
