It is interesting to test this and trace and see the difference of using 5
and _
outp1=: 2
outp2=: 5
trigger=: outp1, outp2
- ^: (trigger */@:-.@e.~ ])^:_ 2 3 5 7
- ^: (trigger */@:-.@e.~ ])^:_ 33
test=: 3 : 0
smoutput 'test'
smoutput y
( trigger */@:-.@e.~ ]) y
)
ft=: 3 : 0
smoutput 'ft'
smoutput ' in comes'
smoutput y
-y
)
( ft ^: (test)^:_) 2 3 5 7
( ft ^: (test)^:5) 33
( ft ^: (test)^:5) 2 3 5 7
( ft ^: (test)^:_) 33
