Agreed that length(@startSite) is WRONG and I didn't say otherwise, but not
"scalar (@startSite)".
If the OP decides to use C style of for loop, this is CORRECT:
for( my $i=1; $i <= scalar (@startSite); $i++ ){ ...
> for my $i ( 0.. $#startSite ) {
The foreach keyword is actually a synonym for the for keyword, so one
can use either.
Please check this: http://perldoc.perl.org/perlsyn.html
Note: foreach my $i (@startSite){...} will also do the same, except
that in the "context" of the OP script, the array index is needed.
