"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!

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.
