"AT" usage, strange..

 [1/4] from: sharriff:aina:med-iq at: 6-Nov-2000 7:47


Hi all! Could someone explain why this happens? (see below)
>> test: [one: "value1" two: "value2" three: "value3" ]
== [one: "value1" two: "value2" three: "value3"]
>> length? test
== 6
>> print at test 3
value2 value3 according to the REBOL dictionary: Provides a simple way to index into a series. AT returns the series at the new index point. Note that the operation is relative to the current position within the series. why are the words in the block not retured also? they are also elements of 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! Andrew Martin ICQ: 26227169 http://members.nbci.com/AndrewMartin/

the moment in New Zealand Andrew? just curious... 6/Nov/2000 10:20PM And I'm writing email for my two PBeMs, plus I've also been playing with groove , available from http://www.groove.net. Which is a Peer-to-Peer text, picture, file, chat, voice-chat application, that I'm sure could be done better in Rebol and quicker! It's a bit slow on my machine and takes 1/2 hour to down load on 56K modem. Andrew Martin ICQ: 26227169 http://members.nbci.com/AndrewMartin/
