Hi List,
I have been "unsubscribed" from the list for a couple of days. Therefore I
have not been able to see the replies to my "change/at" post.
The original problem was to change false to true for the ith position in a
block ( [ false false
false ] becoming [ false true false ]
Romano and Gabriele suggested poke, which I had obviously missed.
Joel Neely's answer was interesting and pointed to another gotcha
>> test: [[0] [0] [0]] == [[0] [0] [0]]
>> i: 2 == 2
>> test/:i/1: 1 == [1]
>> neither of the expressions
>> test: [false false false]
>> nor
>> test: [[false][false][false]]
>> contain LOGIC! values ;-)
Isn't odd ? Because I needed logic! values. I found out that the correct way
to do it was
test: reduce [false false false]
How come it is so ? I frankly do not understand !
Ciao, Patrick
