I created the hash manually to associate the file name with the file - if there's another/better way to do that I'd be very interested to know.

If you must hardwire the filenames, I don't have anything against using a hash to store them. I just might not have bothered with the intermediate scalar variables:

my  $data2="/home/users/some_path/edit/data2.txt";
my  $data1 ="/home/users/some_path/edit/data1.txt";
my  $data3 ="/home/users/some_path/edit/data3.txt";

my %dbs = (
            Data1        =>    $data1,
            Data2        =>    $data2,
            Data3        =>    $data3,
);

...could be written more legibly as:

my %dbs = (
    Data2 => "/home/users/some_path/edit/data2.txt",
    Data1 => "/home/users/some_path/edit/data1.txt",
    Data3 => "/home/users/some_path/edit/data3.txt",
);

But that's, as I mentioned, just a style issue. I may be out of style myself. ;)
