Greetings, Perl control-character gurus. This lowly perl peon seeks advice on what is probably a very simple control char problem... My script takes input from a text box and prints it into an email (sent using unix sendmail). When I send these emails to myself, my email program (Pegasus mail) shows ~nl~ wherever the user hit return in the original text box, yet other parts of the script which generate *html* from the text input work fine. I presume the ~nl~ means newline, so I have tried adding s/// lines to remove \n, \r, cM, etc. Nothing I have hit upon seems to fix this. 
----------------------------
Original code:

sub add_email_message {

$subject = "New Ad";
$message = "The following ad (number $new_counter) was added.

$form_data{'caption_header'} $form_data{'caption'}
$form_data{'text'}

    ...(notice assignment to $message has not reached end quote)... 
------------------------------------------
New code:

sub add_email_message {

$peg_nl = $form_data{'text'};
$peg_nl =~ s/\n/ /g;

$subject = "New Ad";
$message = "The following ad (number $new_counter) was added.

$form_data{'caption_header'} $form_data{'caption'}
$peg_nl

    ...(notice assignment to $message has not reached end quote)...
