你建立根据观测值的为标签，大于多少到那一个文档，就这样你想多少就多少个都可以输出
最好用宏

但具体怎么实现呢，我只懂一点点SAS，谢谢

data _null_;
set shuju nobs=obs;
call symput("obs",obs);
stop;
run;
%macro a;
%do i=1 to &obs by 50000;
%let j=%eval(&i+5000);
%let k=%sysevalf(&j/50000);
liabname xls excel "c:/ttt.xls";
data xls.第&k.页；
set shuju(firstobs=&i ,obs=&j);
run;
%mend;
%a

data _null_;
set sashelp.class nobs=obs;
call symput("obs",obs);
stop;
run;
libname xls excel "c:/tt.xls";
%macro a;
%do i=1 %to &obs %by 2;
%let j=%eval(&i+2);
%let k=%sysfunc(round(%sysevalf(&j/2)));
data  xls.第&k.页;
set sashelp.class(firstobs=&i obs=&j);
run;
%end;
%mend;
%a

这个不懂，还是菜鸟
