Hi,
Could someone point me in the right direction for my below requirement..
I wish to take the sum of variables A: based on the values of the variables START and END.
For Example for the first row in the below dataset the Start value is 1 and End Value is 5 hence the sum is to be calculated for the variables A1 to A5.
Data Have;
input START END A1 A2 A3 A4 A5;
CARDS
1 5 1 2 3 4 5
1 3 1 2 3 4 5
2 4 1 2 3 4 5
;
RUN;
The Final Column to be derived is
15
6
9
Thanks In advance
data want ;
set have;
array a a1-a5;
do _n_=start to end;
total=sum(total,0,a(_n_));
end;
run;
data want ;
set have;
array a a1-a5;
do _n_=start to end;
total=sum(total,0,a(_n_));
end;
run;
Almost the same with Tom's .
Data Have; input START END A1 A2 A3 A4 A5; CARDS; 1 5 1 2 3 4 5 1 3 1 2 3 4 5 2 4 1 2 3 4 5 ; RUN; data want ; set have; array a a1-a5; sum=0; do _n_=start to end; sum+a(_n_); end; run;
