这个宏怎么调用呢？我是菜鸟一枚

in=  is for enter the name of dataset.   
         for example: in=aa

var= is for enter the variable name you want to add and multiple
         for example:    var = var2

out= is for enter the name of output dataset
         for example: out=result

to use the macro, just type  
%sum_prod(In=aa, var=var2, out=result);

then submit it to run.
