This variable returns the number of array elements in @_ - For example:

#!/usr/bin/perl -Tw

use strict;

my @array = (1..5);

#   Pass @array to the &count subroutine and print returned result
#
print "There are ", &count(@array), " elements in \@array.\n";


sub count {

    #   The arguments are passed to &count and are in @_
    #
    return $#_ + 1;
};
