Thanks Ygor, that *almost* works!
The problem I get is that for some reason no values are written to OK.txt
Also, for each line that is run, I get an error similar to this:
./num.sh[26]: 1.3004: not found [No such file or directory]
so for the above value (1.3004) it does not write it to OK.txt
However, it appears to write out the values that it should to BAD.txt for some reason? I don't know if it matters, but I'm running the script in ksh. Thanks!

Hello,
Our group is just starting to get into UNIX here. We are former REXX users on a VM Mainframe. Can someone point me to the documentation to read a file and write a file in a Unix Shell Script or does this have to be done in another language?
Thank you in advance...

net::dns::question
Net::DNS::Question(3) User Contributed Perl Documentation Net::DNS::Question(3)NAME
Net::DNS::Question - DNS question record
SYNOPSIS
use Net::DNS::Question;
$question = new Net::DNS::Question('example.com', 'A', 'IN');
DESCRIPTION
A Net::DNS::Question object represents a record in the question section of a DNS packet.
METHODS
new
$question = new Net::DNS::Question('example.com', 'A', 'IN');
$question = new Net::DNS::Question('example.com');
$question = new Net::DNS::Question('192.0.32.10', 'PTR', 'IN');
$question = new Net::DNS::Question('192.0.32.10');
Creates a question object from the domain, type, and class passed as arguments. One or both type and class arguments may be omitted and
will assume the default values shown above.
RFC4291 and RFC4632 IP address/prefix notation is supported for queries in both in-addr.arpa and ip6.arpa namespaces.
decode
$question = decode Net::DNS::Question($data, $offset);
($question, $offset) = decode Net::DNS::Question($data, $offset);
Decodes the question record at the specified location within a DNS wire-format packet. The first argument is a reference to the buffer
containing the packet data. The second argument is the offset of the start of the question record.
Returns a Net::DNS::Question object and the offset of the next location in the packet.
An exception is raised if the object cannot be created (e.g., corrupt or insufficient data).
encode
$data = $question->encode( $offset, $hash );
Returns the Net::DNS::Question in binary format suitable for inclusion in a DNS packet buffer.
The optional arguments are the offset within the packet data where the Net::DNS::Question is to be stored and a reference to a hash table
used to index compressed names within the packet.
name
$name = $question->name;
Internationalised domain name corresponding to the qname attribute.
Decoding non-ASCII domain names is computationally expensive and undesirable for names which are likely to be used to construct further
queries.
When required to communicate with humans, the 'proper' domain name should be extracted from a query or reply packet.
$query = new Net::DNS::Packet( $example, 'ANY' );
$reply = $resolver->send($query) or die;
($question) = $reply->question;
$name = $question->name;
qname, zname
$qname = $question->qname;
$zname = $question->zname;
Canonical ASCII domain name as required for the query subject transmitted to a nameserver. In dynamic update packets, this attribute is
known as zname() and refers to the zone name.
qtype, ztype
$qtype = $question->qtype;
$ztype = $question->ztype;
Returns the question type attribute. In dynamic update packets, this attribute is known as ztype() and refers to the zone type.
qclass, zclass
$qclass = $question->qclass;
$zclass = $question->zclass;
Returns the question class attribute. In dynamic update packets, this attribute is known as zclass() and refers to the zone class.
print
$object->print;
Prints the record to the standard output. Calls the string() method to get the string representation.
string
print "string = ", $question->string, "
";
Returns a string representation of the question record.
