Subject: "$#{$array} "
Hi,
I don't not understand how the $#{$array_r} returns "highest" element as 4
and not 5???
#!/usr/bin/perl
use warnings;
use strict;
my @array = (1,2,3,4,5);
my $array_r = [EMAIL PROTECTED];
print "the highest element is number $#{$array_r}\n";
FYI ...
SUN1-BATCH>perl -e '@a=(1 .. 5); print "List max index = $#a and has " .
scalar(@a) . " elements\n";'
List max index = 4 and has 5 elements
