in reply to Line ending transformation

Hi ,

The pattern match within the look_ahead and look_behind positive assertions are not included int he pattern itself and hence are not removed .

This is an example of using the $' and $`

You can capture the pattern before the match with $` and after the match with $' and remove it . The above code is just an example of that

I am not sure if you want to do tsomething like this or what , but I am sure the look_behind and look_ahead assertions are not as you have used
if ($_=~ /(\012\015)/){ local $prev = $`; local $nxt = $'; s/$prev//g; s/$next//g; }
