变量中加入分隔符

你可能没有理解我的意思。一个变量有三十个字节而想当然为数据型变量，在sas里是不合理的。并不是我认为三十 ...

Yes. SAS uses floating calculation. The accuracy may not goes to 30 digits. I remember that it goes to 16 (18) digits.

Here is another example which should work for nay length of character value.


data t1;
   z='123456789012345678901234567890';
   output;
   z='12345678901234567890';
   output;
   z='          12345678901234567890';
   output;
run;

data _null_;
   length  v1-v15 $2 y $44;
   array v(*) v1-v15;
   set t1;

   do i=1 to 15;
      v=peekc(addr(z)+(i-1)*2);
   end;
   y=catx(',', of v

);
   put z= ;
   put y= ;
   put /;

run;

非常感谢~

U can use the following code.

data test01;

很有启发！
