Re: Is there a way more easy?

Some good old recursive programming:

    my @a=('', 'a'..'z', 'A'..'Z', '_');
    v("",3,\@a);
    sub v {
        my ($p,$n,$a)=@_;
        if ($n) {
            --$n;
            v($p.$_,$n,$a) foreach (@$a);
        }
        else {
            print $p,"\n"
        }
    }
