[EMAIL PROTECTED] ~]$ perl -Mstrict -Mwarnings -le 'my @arr=qw/aa bb cc/;print $#arr' 2 [EMAIL PROTECTED] ~]$ perl -Mstrict -Mwarnings -le 'my @arr=qw/aa bb cc/;print scalar @arr' 3 They are not the same. The $#arr is the last element's index number,while 'scalar @arr' is all the elements' total number. -- Jeff Pang NetEase AntiSpam Team http://corp.netease.com -- Oops, you're right! Guess I'm still half asleep this morning. But $#arr + 1 is surely another way to get the result sought. That's the way I always do it, not realizing that scalar @arr was even available, I guess. However, scalar @arr is computationally more efficient, I bet, and only slightly longer to write. So it's probably a better way. I'm not exactly a Perl beginner, but looks like I learned something already from this list. Pretty good, seeing I only signed up 3 days ago....
