sas编程

%macro plot; proc means data=shuju.&y mean; var _COL2 _COL3 _COL4 _COL6; output out=&a mean=avg2 avg3 avg4 avg6; %mend plot; %let y=y1; %let a=a1; %plot; %let y=y2; %let a=a2; %plot; %let y=y3; %let a=a3; %plot; %let y=y4; %let a=a4; %plot; %let y=y5; %let a=a5; %plot; %let y=y6; %let a=a6; %plot; %let y=y7; %let a=a7; %plot; %let y=y8; %let a=a8; %plot; %let y=y9; %let a=a9; %plot; %let y=y10; %let a=a10; %plot; %let y=y11; %let a=a11; %plot; %let y=y12; %let a=a12; %plot; run; 我这段程序输出12张y表和12张a表，请问能不能做循环语句，让我不用这样复制黏贴更改，就能输出12张y表和12张a表。

%macro plot;
%do i=1 %to 12;
proc means data=shuju.y&i mean;
var _COL2 _COL3 _COL4 _COL6;
output out=a&i mean=avg2 avg3 avg4 avg6;
%end;
%mend plot;

%plot;

大神，谢谢你。我当初也是想用do语句，但都没成功，这个do语句是只能放在这个顺序吗
