Yes, all rows are complete. To check RegExp, I was printing each new line and after parsing the data to the DB directly was quering for a new entry using unique ID (index). To check each parsed line I use the following code: 
# Display RexExp results
print STDERR join("\t",@arguments),"\n";

<here add all data from @argumens to a DB (as described in the origina
+l post)>

# check if data parsed successfully
my $sql2 = 'SELECT *
    FROM hist_mod_score
    WHERE Counts=?';
    $sth = $dbh->prepare($sql2) or die $dbh->errstr;
    $sth->execute($index) or die $sth->errstr;

# dump fetched query results        
    $sth->dump_results if $sth->{NUM_OF_FIELDS};
