Yes there is - there are many ways in fact. To get started you need to take a look at open, close, perldata (hashes in particular), perlsyn (while loops) and perlop (the diamond operator: '<FILEHANDLE>'), then take a stroll through the Tutorials section here.

When you've done all that and written your first attempt at the code, come back here with any problems you might have.
