Several ways:

 

proc freq data=have;

   tables x1 * x2 * x3 / list;

run;

 

is probably the easiest.

If the number of Xn variables is not known:

 

data temp;
set have;
length cat $32;
cat=cats(of x:);
keep cat;
run;

proc sql;
create table want as 
select cat, count(*) as n
from temp
group by cat;
select * from want;
quit;
