data tmp;
     do i=1 to 1000;
         x=rannor(342);
         output;
     end;
     keep x;
run;
proc univariate data=tmp;
run;

或者

data tmp;
  do i=1 to 1000;
     x=rannor(342);
  output;
  end;
run;
proc sort data=tmp out=b;
   by x;
run;
data want;
   set b;
   if _n_=1 then
   output;
run;

See example below,

data t1;
do i=1 to 10;
x=ranuni(90);
output;
end;
run;
proc print; run;
data _null_;
set t1 end=end;
retain minx position 1e308;
n+1;
if x<minx than do;
minx=x ; position=n;
end;
if end then put 'min=' minx 'location=' position;
run;

假设data是a，变量是x

proc sql number;
select *
from a
having x=min(x);
quit;

Question: 请问如何知道一列变量值中最小值所处的位置？
我的理解是 楼主想得知数据集中第几个OBS处的值是最小值.

data a;
  input x@@;
  datalines;
  10 7 4 8 2 3 9
  ;
  run;

data aa;
set a;
Obs_No=_N_;
run;

proc sql;
select Obs_No as Pos_Min
from aa as b
having b.x=min(x);
quit;
