Hello Dave,

I've only done this stuff from Java however you may find the following 
information 
useful.

\n is NOT a Carriage Return, it is a New Line or Line Feed.  Carriage Return is 
\r.  Some 
languages treat them synonomously (or treat \n like \r\n) but they are 
different.  If you 
debug the data received you should find that it is actually separated by both 
Carriage 
Return and Line Feed (i.e., \r\n).

Also x'15' is not what you should be searching for (x'15' is the DBCS Shift In 
character).  Octal 15 is a Carriage Return but that is x'0D', Line Feed is x'25 
in EBCDIC 
and x'0A' in ASCII.  Since the data sent from a browser is ASCII you probably 
should be 
searching for the ASCII code-points.

As I said earlier, debug the data received by your comment parser and see what 
is 
actually in the data stream.  I think most of your trouble is because you are 
not 
searching for the correct delimiter.  Search for \r (x'OD') and add 2 to get 
the start of 
the next comment.

Regards,
Simon Coulter.
