What you want is <@I. '0'=":example . You don't want &.> because verbs
derived from it have rank zero, and I. doesn't make
sense on scalars ( I. needs to look at a whole list; I.&.> can only look at
an atom at a time).
The reason <@I. works without needing the rank conjunction is because I. is
already rank one:
I. b. 0
1 _ _
If it weren't, you'd need the rank conjunction. For example, let's say I.
were instead defined with rank infinity:
I =: I."_
then you'd need to say something along the lines of <@:I"1 '0'=":example .
Or, say you wanted to take advantage of the special
code which supports I.@:= . Then you'd need to say '0' <@:(I.@:=)"1
example.
Does that help?
