Hi all,
I have a question about arrays.
I have a data set that looks similar to this only much bigger (1000x) I need to calculate the combine scores of [a, b ,c ....n] based on a set equation [ ((n)x + (n)y) - Fixed]. I have created an array for it but I failed to obtain the answer:
The dummy data and the ideal outcome:
Data have | Ideal | |||||||||
Fixed | ax | ay | bx | by | cx | cy | a | b | c | |
6 | 13 | 21 | 12 | 16 | 11 | 10 | 28 | 22 | 15 | |
13 | 14 | 21 | 15 | 10 | 15 | 10 | 22 | 12 | 12 | |
1 | 16 | 11 | 20 | 19 | 15 | 15 | 26 | 38 | 29 | |
10 | 14 | 14 | 18 | 17 | 17 | 17 | 18 | 25 | 24 | |
16 | 10 | 14 | 10 | 13 | 12 | 21 | 8 | 7 | 17 | |
17 | 19 | 16 | 17 | 11 | 13 | 20 | 18 | 11 | 16 | |
7 | 11 | 12 | 15 | 19 | 21 | 20 | 16 | 27 | 34 | |
2 | 16 | 21 | 17 | 11 | 15 | 14 | 35 | 26 | 27 | |
11 | 20 | 17 | 17 | 14 | 12 | 20 | 26 | 20 | 21 | |
19 | 12 | 11 | 10 | 17 | 11 | 21 | 4 | 8 | 13 | |
6 | 12 | 20 | 10 | 12 | 17 | 13 | 26 | 16 | 24 |
The code:
data have;
input Fixed ax ay bx by cx cy;
datalines;
6 13 21 12 16 11 10
13 14 21 15 10 15 10
1 16 11 20 19 15 15
10 14 14 18 17 17 17
16 10 14 10 13 12 21
17 19 16 17 11 13 20
7 11 12 15 19 21 20
2 16 21 17 11 15 14
11 20 17 17 14 12 20
19 12 11 10 17 11 21
6 12 20 10 12 17 13
;
run;
data want;
set have;
array xcal (*) ax bx cx;
array ycal (*) ay by cy;
array wnt (*) a b c;
do i=1 to dim(xcal);
do j=1 to dim(ycal);
do k=1 to dim(wnt);
wnt(k) = (xcal(i) + ycal(j)) - fixed ;
end;end;end;
drop i j k;
run;
and the wrong outcome:
Fixed | ax | ay | bx | by | cx | cy | a | b | c |
6 | 13 | 21 | 12 | 16 | 11 | 10 | 15 | 15 | 15 |
13 | 14 | 21 | 15 | 10 | 15 | 10 | 12 | 12 | 12 |
1 | 16 | 11 | 20 | 19 | 15 | 15 | 29 | 29 | 29 |
10 | 14 | 14 | 18 | 17 | 17 | 17 | 24 | 24 | 24 |
16 | 10 | 14 | 10 | 13 | 12 | 21 | 17 | 17 | 17 |
17 | 19 | 16 | 17 | 11 | 13 | 20 | 16 | 16 | 16 |
7 | 11 | 12 | 15 | 19 | 21 | 20 | 34 | 34 | 34 |
2 | 16 | 21 | 17 | 11 | 15 | 14 | 27 | 27 | 27 |
11 | 20 | 17 | 17 | 14 | 12 | 20 | 21 | 21 | 21 |
19 | 12 | 11 | 10 | 17 | 11 | 21 | 13 | 13 | 13 |
6 | 12 | 20 | 10 | 12 | 17 | 13 | 24 | 24 | 24 |
Could anyone advice me the right method or find out what is wrong with my code please?
Many thanks in advance!

You just have too many DOs.

Hi,
I think only one do loop will do the job.
data want;
set have;
array xcal (*) ax bx cx;
array ycal (*) ay by cy;
array wnt (*) a b c;
do i=1 to dim(xcal);
wnt(i) = (xcal(i) + ycal(i)) - fixed ;
end;
drop i;
run;
proc print data=want;
run;
