Searching files opened by Perl Scripts -> HELP

[Sonahl]

Hi, I need help using Perl. I've tried looking through websites, but to no
avail. See, my program is supposed to search a phonebook depending on certain
criteria. I was able to create the phonebook, I was able to add entries to the
phonebook, but now, I don't know how to search the phonebook using the Perl
script. 

Usually, without a perl script, I'd use the command

grep Ray phonebook 

which means to display lines that contain "Ray" in it, but now, I just don't
know how to go about doing this. If you can help, I'll greatly appreciate it.
