after data set,
Name sex weight
1 tom male 200

我的想法是：
data libnam.c9501;
set data libnam.c9501x;
if name^=name;
run;
可是不能实现， 跪求高手指教。。。。。。。。作者: shiyiming 时间: 2006-7-29 16:10 标题: to lxlinxu 是不是想把完全相同的记录去除掉？
试试看proc sort data=libnam.c9501 nodup;这个选项。作者: shiyiming 时间: 2006-7-30 01:19 标题: to shiyiming 谢谢，我试一下先。作者: shiyiming 时间: 2006-8-3 08:32 标题: thanks alot it really works. i appriciate that... thank u, mr. shiyiming...
