G'day jalopez453,

As has already been mentioned, you've some problems in your code. Another, is "untie @array" inside the for loop: indenting your code probably would have made that more obvious.

If you have a different number of new headers than what was there originally, consider using splice. Here's a quick example:

$ perl -E '
    my @x = qw{H-old ...};
    say for @x;
    splice @x, 0, 1, qw{H-new1 H-new2};
    say for @x;
'
H-old
...
H-new1
H-new2
...
