in reply to Updating a binary value in Net::LDAP

If we call it an "octet string", instead of "binary", a concatenated octet string can be generated and stored like this (untested): 
use Socket qw( inet_aton );
...
   fileStore => join ('', map {inet_aton $_} @mynets),

This will be a concatenated string of 32-bit binary IP addresses (assuming IPv4), and can be written to a file.

    Many thanks NetWallah,

    Looking at my original post I neglected to point out that the output sound have been a list of IP addresses with the text " OK" appended to each entry so the inet_aton() function was not going to work. However your suggestion to use the map() function was exactly what I needed and with your guidance the code below does what I need: 

    fileStore => join ('', map {$_ .= "\tok\n" } @mynets),

    Just what I needed, thank you for your speedy response.
