Just a few points.

It's no longer necessary to seed the RNG with srand, that has been automatic for the last few versions of Perl.

The @Chars array can be initialized with the list range operator: 

my @Chars = '0'..'9', 'A'..'Z', 'a'..'z';

I'd rename $l so it doesn't look like the first captured match builtin, $1. It could also be generated by 

$l = join '', map {$Chars[rand @Chars]} 1..7*($ARGV[0] ||= 1);
