That said, it's also worth noting that a single explicit loop could also be used here. For example, |
|||
<syntaxhighlight lang=J> |
|||
charcols=: {{ |
|||
'one two three'=. y |
|||
for_a. one do. |
|||
echo a,(a_index{two),":a_index{three |
|||
end. |
|||
}} |
|||
charcols 'abc';'ABC';1 2 3 |
|||
aA1 |
|||
bB2 |
|||
cC3</syntaxhighlight> |
