Almost. That has a off-by-one error, as $i should not be equal to
scalar(@startSite). I believe the following is correct:
for( my $i=1; $i < scalar (@startSite); $i++ ){ ... }
Since the '<' operator provides scalar context on both sides, this may be
simplified to:
for( my $i=1; $i < @startSite; $i++ ){ ... }

This is the same except that it starts with 0, not 1, and you cannot modify $i
with any effect within the loop, as you can with the C-style for loop, which
may be relevant for some applications.
