Sample 35452: Calculating the product for a single variable or across variables
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

Since reporting procedures, such as MEANS, SUMMARY, REPORT, and TABULATE, do not have a statistic to calculate a product, this type of calculation can be accomplished by reshaping the data and using ARRAY logic.
