Ok, I think I more or less have it. The true grocking of the hash,
well, that I think will come in time with reading and experience.
Thank you all for the help and pointers!

may not be other references to that array elsewhere in the program

Greets.
I have a 'config file' that contains a group name (alphanumeric) and
machine name/numbers separated by whitespace. Each group is on it's
own line. The file looks like this:
prod01 456 345 234
prod02 789 517 325
...etc, etc, etc...
What I am attempting to do is:

Hi,
Rather than a dynamic array,you just need to use a correct datastru,a hash.
It's maybe better to write codes as below.
[tmp]$ cat groups.txt
prod01 456 345 234
prod02 789 517 325
prod03 789 517 325
prod04 789 517 325
prod05 789 517 325
[tmp]$ cat test.pl
#!/usr/bin/perl
use strict;
use

Add the name of the array to a 'master array' list of the machine

Then create another array, which would be referenced by the group
name, and contains the machines associated with the group.
