Holli,
You are really helpful.Thanks.I also would like to know how does this make differnece?.Just curious.Does using of HASH reduce the process time.
I am just a beginner.Please bear with me.
Thanks
there is no hash involved in this code, but a regular expression. if you want to know about hashes, read perldata. If you want to know about regular expressions read perlretut, perlrequick and perlre.
