This works, but it strikes me as a bit *too* clever: my $count = () = split(/\s+/, $line, -1); If you've forgotten, a negative third argument forces split to produce all of the possible fields, keeping trailing null fields. In particular, it ignores the size of the destination list. I've more often seen this empty list idiom in conjunction with m//g--not that it's tremendously common there, either. -- Eric Amick Columbia, MD _______________________________________________ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
