如何把一个变量分割成两个变量

shiyiming

譬如说我有一组变量
group_all
1
2
3
4
5
6

怎样才能变为
group1     group2
1                  4
2                  5
3                  6


多谢啦

data bds cds;
set ads;
if group_all <=3 then output bds;
else output cds;
run;

data bds(rename=(group_all=group1 ));
set bds;
i=_n_;
run;

data cds(rename=(group_all=group2 ));
set cds;
i=_n_;
run;

data dds;
merge bds cds;
by i;
drop i;
