PUT 语句中的 OVERPRINT causes the values that follow the keyword OVERPRINT to
                     print on the most recently written output line.
PUT 语句中的 OVERPRINT 将 OVERPRINT 后面引号内的字符打印在前面的输出行下面.
         OVERPRINT 可以与列指针＠配合使用.
Example:
data ;
  put 'L1: '  'example of overprint ' overprint  '------------------------';
  put 'L2: '  'example of overprint ' overprint  '----' ;
  put 'L3: '  @10 'example of overprint ' overprint  @10 '====================' ;
  put 'L4:    ' 'example of overprint ' overprint  @10 '====5====0====5====0' ;
  put 'L5: '  @10 'example of overprint '  @10 '____________________' ; /* NO OVERPRINT */
run;

*  LOG *
L1: example of overprint
------------------------
L2: example of overprint
----
L3:    example of overprint
      ====================
L4:    example of overprint
      ====5====0====5====0
L5:    ____________________
