hi all,
data t;
input m;
cards;
5
4
11
;
data t2;
set t;
k=m+;
output;
run;
I want result like this:
m k
5 5
4 9
11 20
data t;
input m;
cards;
5
4
11
;
data want;
set t;
retain k;
k+m;
run;
proc print;run;
Linlin
what is the purpose of retain statement?
Is K initially assume as zero?
Should I do following if I want to initial k value other than zero?
data want;
set t;
k=2.4;
retain k;
k+m;
run;
hi ... if you don't want to set an initial value, you can skip the RETAIN statement since a SUM statement (K+M) implies retain and starts with an initial value of 0
if you want to set an initial value ... RETAIN K 2.4;
