Hi Monks, I'm new in Perl, I mean very limited know-how in Perl as of now. I hope you can help me with my problem formatting my multiple line data below:

It's a sequence of lines beginning with "Arrival Time", "From:", "To:" and sometimes but not always "User-Agent". In such cases, I need to substitute "--"

I'm using 5.18 for windows.

Your response is very much appreciated.

Thank you in advance
