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

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