the block "test" and therefore also indexed?
>> test: [one: "value1" two: "value2" three: "value3" ]
== [one: "value1" two: "value2" three: "value3"]
>> length? test
== 6
>> at test 3
== [two: "value2" three: "value3"]
>> reduce at test 3
== ["value2" "value3"]
>> print [two: "value2" three: "value3"]
value2 value3
>> two
== "value2"
>> three
== "value3"
Check out page 83 of the Core manual, about 'print using 'reduce as part of
it's operation.
I hope that helps!
