写的语句，就是基础入门练习
VARIABLE:names are a b c;
     USEVARIABLE=suit handle effect；
  DEFINE:suit=a;
         handle=b;
         effect=c;
  ANALYSIS:Bootstrap=1000;
  model:effect on habdle suit;
        handle on suit;
  OUTPUT:standardized;
显示的错误，完全不知道该怎么改了
*** WARNING

  OUTPUT:standardized;
  TITLE: this is an example of a path analysis
   DATA: FILE IS C:\Use
