SOLVED! Simple school-boy error. Was an issue with Windows EOL instead of 'Nix. Thanks to those who attempted to assist :)

Hi guys, I'm having issues with something which should be extremely simple, but is completely doing my head in.

I'm reading in a data file, which consists of 5 fields, separated by colons. I need to add a couple of zeros at the end of two of the fields (they are date/time fields, which need to have the "seconds" added to them for compliance with importation rules). The first instance of me doing this works fine, but for some reason the second instance, on the last field, is doing some funky stuff.</>

So - this works for testing:

my $data_fix = "00";

while (<DATA>)
    {
    my($data1,$data2,$data3,$data4,$data5) = split(/:/);
    chomp($data5);
    $data5 = $data5 . $data_fix;
    $data_line = $data1 . ":" . $data2 . "00" . ":" . $data3 . ":" . $
+data4 . ":" . $data5 . "00" . "\n";
    print $data_line;
    }

__DATA__
o:200806050852:b7199767:b24211012077030:200902232359

And this doesn't work:

my $data_fix = "00";

while (<>)
    {
    my($data1,$data2,$data3,$data4,$data5) = split(/:/);
    chomp($data5);
    $data5 .= $data_fix;
    $data_line = $data1 . ":" . $data2 . "00" . ":" . $data3 . ":" . $
+data4 . ":" . $data5 . "\n";
    print $data_line;
    }

What am I missing here, please??

UPDATE:

It would seem that it has something to do with the way I am accepting the data into the script. When running the script as shown above the the __DATA__ tag internal, it works fine. But when passing that exact same data in with a "cat" call, and changing my while(<DATA>) to while(<>), it breaks...

I'll clean up the above to hopefully simplify where I'm at now.
