Fellows, I am a graduate student who has been away from Perl for 3 or 4 years, and am in need of some assistance. I've got a flat-file (text) database that I need to count the # of tornado days (there is a numeric date field in MM/DD/YYYY format) for each state (a numeric field with each state having a unique ID from 1 to 50)...but the data is arranged by tornado report (such that there are many cases where there are more than 1 tornado per day per state)...so I am looking to count just unique records (1 per day per state) for each year of record, display the results. If anyone could give me any tips on how to get started on this task, it would be much appreciated. Have a good evening, Gordon
