well, the best way would be for you to find out why you're inputting an empty
string as a "%d" argument to sprintf, and avoid that. If you want this "" to be
treated as zero, you can do:
my $c_s = sprintf("%d_%d", ($cell || 0), $sector);
Assuming $cell is the offensive one. (or the same for $sector).
