i mean didnot work didnot perform what i was expected to delete lines from file
as you provide here : 

my $comment = 0;
my $block   = 0;

while(<$in>) {
    if (/^zone\s+"$targetdomain"/) {
        $comment++;
        $block += () = /(\{)/g;
        # print $out '// '.$_;
        next;
    }
    if($comment) {
        $block += () = /(\{)/g;
        s!^!// ! if $comment or $block;
        $block -= () = /(\})/g;
        $comment = 0 unless $block;
    }
    print $out $_ unless $comment;
}

you comment print statement to deny the comments and then use print $out $_ unless $comment; which is completely logical
but when i run it didn't delete the zone .....,
i think i need to provide something that written inside a loop to replace the lines of the zone with space like 
s///;

what do you think about that?
thanks shmem for your great support
warm regards
