Hello , I have this script that when I run it against this zone file I get this error

==> CMS.LAN.db -v Internal

Can't use an undefined value as an ARRAY reference at /local/bin/ line 110, <> line 1709.

Can anyone have a look to see whats the issue?

The error message is telling you that $rrs{$zone} is undefined.

More specifically, CMS.LAN (which is what $zone resolves to) is not a key of the %rrs hash.

Perl is case sensitive, so a hash key of 'CMS.LAN' is not the same key as 'cms.lan'.  Your %rrs hash does have a 'cms.lan' key.

So, maybe all you need to do is lowercase $zone either when it's being assigned or when you use it in the join statement on line 110.

my $dclist = join ( ", " , @{ $rrs{lc $zone} } );

Ok. Just want it to run without an array issue. Can that me done ? Or have the script compensate for capital letters ?

My #39969334 post shows how to compensate for capital letters in $zone.

However, since you haven't explained what your output expectation is, I can't say if there are any other adjustments that will be need to be applied.
