There is not a SAS statistic or function to calculate the product of a
variable or across variables.  The sample below demonstrates this 
technique for calculating the product of one variable. 

/* create sample data */
   data test;
     input x @@;
   cards;
   1 2 3 8 9 21 11
   ;
   run;

/* reshape the data */
   proc transpose data=test out=out;
     var x;
   run;

   data out;
     set out;
     array test(*) _numeric_;
     prod=1;
     do i=1 to dim(test);
       prod=prod*test(i);
     end;
     drop i;
     run;

   proc print;
   run;

 
To calculate the product for all numeric variables in a data set across
observations, the DATA OUT step above is all that is needed with the 
appropriate data set name on the SET statement. 

Below are two other SAS notes that also calculate the product.

SAS note 24628

SAS note 41557
