[REBOL] 'Foreach questions
From: tim::johnsons-web::com at: 21-Dec-2002 11:29
Fellow Rebols:
I'm trying to use the same block of words in both a query
and in parsing data from the query. To illustrate here's some
test data, some results and some results I'm looking for...
; need some words set to literal values
>> col-names: set [a b c d] ["one" "two" "three" "four"]
== ["one" "two" "three" "four"]
; now some test data. Let's pretend that this data is retrieved
; by a query using col-names above
>> data: [[1 2 3 4] [5 6 7 8] [9 10 11 12]]
== [[1 2 3 4] [5 6 7 8] [9 10 11 12]]
; now I want to fetch each inner block in 'data and
; automagically set each word in 'col-names to each successive
; item in the inner block
>> foreach row data[set 'col-names row
prin mold col-names prin mold a
prin mold b prin mold c print mold d
]
[1 2 3 4]"one""two""three""four"
[5 6 7 8]"one""two""three""four"
[9 10 11 12]"one""two""three""four"
; alas, I've failed to get what I wanted. What I wanted to see is:
[1 2 3 4] 1 2 3 4
[5 6 7 8] 5 6 7 8
[9 10 11 12] 9 10 11 12
; where each 'word originally in col-names would be set to
; a return value
Any ideas on how I can make this work for me in a similar
fashion.
TIA
