`$#array + 1` is wrong. $#array is the index of the last element in @array. It is normally one less than the number of elements in the array, but not always, as it assumes that array indices start at 0. If `$[` is set then that is not necessarily the case.	[reply] [d/l] [select]

What's wrong with: `$length = @array;` [download] For example: `#!/usr/bin/perl use strict; my @array = qw(one two three); my $length = $#array + 1; print "Dollar pound array = $length\n"; $length = @array; print "At symbol array = $length\n"; __DATA__ {C} > test.pl Dollar pound array = 3 At symbol array = 3` [download]	[reply] [d/l] [select]
