Here is the project description. analyze the unsolicited traffic hitting 
my front door to determine if the same source ip address is cycling 
through a range of ip address on a hourly, daily, weekly basis. My test 
box ipfilter firewall uses "keep state" on everything that is allowed 
out. Nothing is allowed in. Using ipfilter ippool in-core ip address 
table to capture count of times said unsolicited inbound source ip 
address hits my front door. Have 3 flat text files containing about 2000 
ip address having a record size of 30 bytes.
I am afraid I may be approaching the max file size that csh can handle.
Thinking of simple db where the 3 files are indexed and can be 
read/written with out sequentially process all the records. At the proof 
of concept stage.

I have programmed in pear script before where I can open a file and 
process a record sequentially where only the next record is buffered. 
csh does not have that kind of file handling that I know of.

You have any suggestions?
