宏引用的位置

shiyiming

[code:2buh2eqn]%macro COLS1;  
     Name Age;
  %mend;      
  %macro COLS2;  
     Height Weight;      
  %mend;      
  proc print data=SASHELP.CLASS;
     [_insert_VAR_statement_here_]        
  run;  [/code:2buh2eqn]
有4个选项：
  A. var %COLS1 %COLS2;      
   B. var %COLS1-%COLS2;      
   C. var %COLS1 Weight Height;        
   D. var Weight Height %COLS1;
想问的问题是，为什么宏引用不能直接放在var后面呢？望高手们解析下...

should work well if you change your macro like this, just remove the semicolon ';' :
%macro COLS1;  
     Name Age
  %mend;      
  %macro COLS2;  
     Height Weight   
  %mend;
