hdb: I could only get that to work my changing it to..

open(my $in_fh = IO::File->new, "<", $infile) 
or die "Can't open $infile: $!.\n";

close $in_fh;

my $chunk =~ s/[\f\r\n]//g;
my @statement = split '`', $chunk;

## %desc stuff here
my %data;
$/ = "`\n";
foreach my $line (@statement) {
..
}

instead of:

my %data;
$/ = "`\n";
foreach my $line (<DATA>) {
..
}

Is %data set to the file variable in your version? I think shifting the first field may be a mistake of mine, too. Doing this doesn't parse the 200~ fields. my output was:

Unknown data 020000000123
Unknown data 500
Unknown data 300
Unknown data 510
Unknown data 539
Unknown data 510
