I prefer:

	for (my $ii = 0; $ii < @temp; $ii++) {

$#temp is the last array index of @temp.  By using @temp instead (in a 
scalar context) you get the full array size and can use < instead of <= 
for the comparison.  If @temp has 6 elements, $# is equal to 5 (the index 
of the last element of the array).
