[localhost:~/Programming/Perl/Various code] tor% cat argv.pl
#!/usr/bin/perl -w
for (@ARGV) {
push @ARGV;
print "$_\n";
}
[localhost:~/Programming/Perl/Various code] tor% ./argv.pl 2 3 bananas
apples

You can use the $ARGV[X] values directly like above, or you can put them in
variables. I guess that's what drieux did. Everything passed from the
command line are put into to the @ARGV array.
So, when I write
% ./argv.pl 2 3 bananas apples
@ARGV looks like this: qw(2 3 bananas apples)
