Listmates:

	I don't know who I have to thank for this, but I think it was Anders who 
recommended that I look at perl after one of my last weird bash questions. I 
have a syntax question as I go though perl.

        The situation. I read a file into an array and then go to reference 
each line.

my $NUM = 1;
open FILE, ".bashrc" or die $!;
my @array = <FILE>;

	How is it legal that I can reference the array element either as 
@array[element] or $array[element]?:

while (@array[$NUM]) {
        print "$NUM : @array[$NUM]\n";
        $NUM++;
}

while ($array[$NUM]) {
        print "$NUM : $array[$NUM]\n";
        $NUM++;
}

	From what I've read, it seems like the list $array[element] would just return 
the number of characters in the list $array[element] not the text itself. How 
should I think about this?
