SAS - I would like to count characteristics across variables - sas

Question

I have a data set which essence is the following
data have;
input Name $ ab gh vz iz jh pq ch km eo lk;
datalines;
adam 7 8 7 0 0 0 0 0 0 0
bob 0 1 0 3 4 6 0 1 6 0
clint 0 0 0 5 4 3 1 0 0 2
;
run;
Now I would like to count how many times I have a number greater than zero in the variables iz, jh, chand km. The result should look like this
/* want
Name ab gh vz iz jh pq ch km eo lk count_of_iz_jh_ch_km
adam 7 8 7 0 2 3 0 0 0 0 1
bob 0 1 0 3 0 6 0 1 6 0 2
clint 5 0 0 5 4 3 1 2 0 2 4
*/
I would greatly appreciate any help since I wasn't successful searching the internet for a solution.

Answer 1

The below code will initialize the required variables from have into an array called vars, then for each row, count every time one of these variables is > 0.
data want;
set have;
array vars[*] iz jh ch km;
count_of_iz_ch_km = 0;
do i = 1 to dim(vars);
if(vars[i] > 0) then count_of_iz_ch_km+1;
end;
drop i;
run;
