SAS do loop問題

Question

這是我的代碼：

libname Project 'XXX'; run;
%let dname = q1males;
%let Gender = 'Male';
%let samp = q1msamp;
%let stats = Malestats;


data project.data1; set project.data;
id = _n_;
run;



data project.&dname; set project.data1; 
if Gender = &Gender;
run;
%macro question;
%do i = 1 %to 5;

proc surveyselect data = project.&dname method = SRS sampsize = 27 
                out = project.&samp;
                id _all_;
run;

proc print data = project.&samp;
run;

proc sql;
create table project.&stats&i as
select 'Weight',
avg(Weight) as Mean format 10.2 label 'Mean Weight',
std(Weight) as Std format 10.2 label 'Std. Dev Weight'
from project.&samp;
QUIT;
%end;
%mend question;
%question;

%do j = 1 %to 5;
data project.merged&j;
merge project.femalestats&j project.malestats&j;
by _Tema003 Mean Std;
run;

除了最后6行外，一切都正常，從％do j = 1％到5開始。我對雌性和雄性數據集運行了兩次代碼，而后6行我試圖合並雌性和雄性數據集（例如：project.Femalestats1與project.Malestats1合並到新的數據集project.merged1中。）我的日志沒有顯示錯誤，但是我也沒有得到合並的數據集。 我嘗試了proc sql，結果令人失望。

有什么幫助嗎？ 謝謝！

您不能在宏外部使用宏循環。 像處理question宏一樣，將最后一行括在宏中。

另外，您需要結束循環：

%macro myloop();
   %do i=1 %to 5;

      <stuff>

   %end
%mend;

%myloop;
