I guess the bigger question is why loop thru the file multiple
times? You should be able to gather all that you need on one pass and
either move into a hash or array depending on what you need. It may be a
small file now, but if you get into the habit when a large file is
needed to be processed and you start doing mulitple reads, then you may
have problems with cpu or io increase. May be a legitimate reason, but I
would learn to get what is needed on one pass and then work with a hash
or array.
If you have any questions and/or problems, please let me know.
Thanks.
