Subject: Dynamically creating variables

Hi all,

I'm fairly new to Ruby, and programming in general (though I'm 
reasonably proficient at shell scripting) so sorry if this is a dumb 
question.

I'm trying to write a script for an SNMP poller but I'm getting stuck 
trying to work out how to create my variables. The script will be 
processing a CSV of unknown length. It might be just 2 servers or it 
could be up to 20. I cant work out how I can find the list of servers 
from the CSV and then create variables for each one that I can keep 
track off through out the programs life to out put what I want.
this is what I've created so far
http://pastebin.com/bLPbnRv4
I envision it parsing a CSV like this

--
host,port,community,cluster,shortName,type,rpsTotal,clientTotal,serverTotal
172.16.0.1,161,Public,Library,mwg1,mwg7,0,0,0
172.16.0.1,161,Public,Library,mwg2,mwg7,0,0,0
--
after each run, it will need to update the CSV with the results of the 
last poll as those are used to calculate the average throughput between 
each time the script is called.

The whole process will be called as a cron job, and will be outputting 
an HTML file.

Reading around has not really helped me as I've not found any examples 
of others doing this, though I cant imagine others are not.

If any one can give me some pointers, that would be really helpful.

Thanks,

Tris
