Your question is not very clear

一个笨方法：

data test;
   length var $50. ;
   infile 'C:\test.txt'  length=lv ;   
   input  var   $varying50. lv;
   num1=scan(var,1,' ');
   num2=scan(var,-1,' ');
   len=length(var);
   start=length(num1)+1;
   end=length(var)-length(num1)-length(num2);
   str=substr(var,start,end);
   keep num1 str num2;
run;

中间的字符都归为一个character variable?

多谢，看来我两个关键字还是记住了，不过没有记住怎么用哈哈
