Hello All,
 
Below is snippet from a design file for a conjoint analysis.
 
data test;
input text $50.;
cards;
1 1 8 25 0
0
2 1
1 1 1 2 3 2 3 5
2 3 3 3 1 1 2 4
2 0
;
run;
 
I'd like to do a find and replace that changes some of the values in lines with length = 15 (lines 4 and 5 in this example) according to the following set of criteria:
 
position     action
1              do nothing
2              1=3,2=2,3=1
3              1=3,2=2,3=1
4              do nothing
5              1=3,2=2,3=1
6              1=3,2=2,3=1
7              1=3,2=2,3=1
8              do nothing
 
where position is the location of the number within the text string.
 
Does anyone now a good way of doing this?
 
Thanks,
 
Paul
