You have already found the correct forks (>. - <.) and ([: | -).
I just wanted to point out that your example below works, but you have
called the monadic case.
For:
PosDiff =: (] >. [) - (] <. [)
Try:
4 PosDiff 3
3 PosDiff 4

Subject: [Jgeneral] PosDiff =: (] >. [) - ([ <. ]) NB. this is not a fork?
Here is the definition of positive difference that works:
PosDiff =: 4 : '(x >. y) - (x <. y)'
I tried to create a version which is a fork, but it is returning 0 0 instead
of differencing them:
PosDiff =: (] >. [) - (] <. [)
PosDiff 4 3
0 0
PosDiff 3 4
0 0
