have:
x = 11, y = 7, x = 3
want:
x = 11, y = ., x = .
is it possible to enforce this behaviour?
I would use a data step:
data want;
set have;
retain sum_x sum_y sum_z 0;
sum_x = sum_x + x;
sum_y = sum_y + y;
sum_z = sum_z + z;
drop x y z;
run;
I assume by "bigger" you mean that you have a lot more variables.
If so, you can use an array
data want;
set have;
array x(*) var1-var200;
array sum(*) sum1-sum200 (200*0);
do i=1 to dim(x);
sum(i)=sum(i)+x(i);
end;
drop i;
run;
