When values that are checked with the MIN or MAX function are equal, the last variable that contains the minimum or maximum value is output.

The sample code below shows this behavior when using the MAX function.

   data test;                                 
      input orderid var1 var2 var3;              
      datalines;                                 
   1 3 5 5                                    
   ;
   run;                                          
                                              
   data test2;                                
      set test;                                  
      array v(3) var1-var3;                      
      maxval=max(of var1-var3);                  
      do i = 1 to 3;                             
         if v(i)=maxval then whichvar=vname(v(i));
      end;
   run;                                       
                                              
   proc print;                                
   run;
