这段代码根据id的值不同输出不同的datasetname。现在还需要把每个新dataset里的列return改为相应的return1,return11,return1001,return2001....
data fund.fund1
fund.fund11
fund.fund1001
fund.fund2001
fund.fund2011
fund.fund3003
set fund.jingzhitest2;
keep id riqi  danweijingzhi leijijingzhi return;
select(id);
when('1') output fund.fund1;
when('11') output fund.fund11;
when('1001') output fund.fund1001;
when('2001') output fund.fund2001;
when('2011') output fund.fund2011;
when('3003') output fund.fund3003;
run;

请各位专家帮忙。

fund.fund2001
fund.fund2011
fund.fund3003
set fund.jingzhitest2;
keep id riqi danweijingzhi leijijingzhi return;
if id=1 then output fund.fund1;
if id=11 then output fund.fund11;
...
if id=3003 then output fund.fund3003;
run;
