This looks like a fixed length record. You could use unpack. While the following 'demonstrates' the idea it's probably not the best use of unpack (e.g. there's a floating point number). Your best bet would be to ask another question to find an elegant use of unpack. 
#!/bin/perl5
use strict;
use warnings;

my @history = <DATA>;

for my $record (@history){
  print "$record\n";
  $record =~ s/^\s*//;
  my @fields = unpack "a21 a9 a9 a2 a13 a8 a9 a9 a4 a5 a6", $record;
  for my $field (@fields){
    print "*$field*\n";
  }
}

__DATA__
                    AP040003EZ9891783    61125    N        BX    108.0

When you've cracked it you could probably apply it to the other records as well.
