建資料或讀資料

說明：資料本身有 contain semicolons

Use the DATALINES4 statement 範例如下

libname two "d:\test\two";  
filename file1 "d:\test\two\DAY1.sas";  
data a ;  
  length code $100.;  
  input code &  $ ;  
  file file1 ;  
  put code $ ;  
datalines4;  
%Macro DAY1() / store source des="a test for store macro";  
  %put 今日是 &sysdate;  
%Mend DAY1;   
;;;;   
run;  

input code & 這裡面的 & 很重要，沒放的話，遇到 space 就不讀了，變成
%Macro
%put
%Mend
