Congratulations,  You have just moved into the world of SAS macros.  You
may want to read up on the subject, but your sample would look like
this:
 
%LET N = 5;
data new;
        array score(&n) score1-score5 (1, 2, 3, 4, 5);
        do i = 1 to &n;
                .
                .
 
                .
        end;
