array cns (15,72) c1s1994--c1s2065
                                        c2s1994--c2s2065

                                        c11s1994--c11s2065
                                        c12s1994--c12s2065
                                        c13s1994--c13s2065
                                        c14s1994--c14s2065
                                        c15s1994--c15s2065;
array cns_sum (15) c1s_sum c2s_sum c3s_sum c4s_sum c5s_sum c6s_sum
c7s_sum c8s_sum c9s_sum c10s_sum c11s_sum c12s_sum c13s_sum c14s_sum
c15s_sum;
do i=1 to 15;
                cns_sum(i)=sum(of cns(i,1-72));
end;

I also tried, with no luck:

cns_sum(i)=sum(of cns(i,1)--cns(i,1));
