The script works fine if I use "./<script_name> data_file". But when I hardcode the name of data_file, it doesn't work. I am sure it has something to do with "while (<>)" statement. Can anyone please advice how to proceed when we have datafile name hardcoded, and it is read in an array and then.......???
