I want to create variable sum where sum add the number from n and below like this:
2 Sum=2+2+3+2+4
2 Sum= 2+3+2+4
3 Sum= 3+2+4
2 Sum= 2+4
4 Sum=4
2) And how Do I do this. I want to add 2, 2(2) t the terms in t as I go dowm. Creating variable m.
data AA;
input t;
cards ;

to
data AA;
input t m;
cards ;
1 1+2
1 1+2(2)
1 1+3(2)
1 1+4(2)

I'm confused! I thought the code I suggested DID preserve the order in both cases.
data CP;
input t;
recnum=_n_;
cards;

;
proc sort data=cp out=aa;
by descending recnum;
run;
data aa;
set aa;
sum+t;
run;
proc sort data=aa (drop=recnum);
by descending sum;
run;
data bb;
input t;
m=t+_n_*2;
cards ;
