LYNX-DEV Two bugs in Lynx,

        Okay, thanks.  I got what I needed.  However I've run into two
problems/bugs in lynx.

First:  In lynx 2-7, imbedding the username and password in the ftp URL does
not work.  The same command works fine with 2-6 and 2-5.  
Here's my command
lynx ftp://username:address@hidden/

The same command line works fine under 2-5 and 2-6, however it does NOT work
under 2-7.  If you do a trace you can discover it's trying to do a DNS
lookup on username:password.  Something is busted here.

Second:  There is a problem in the HTFTP code in lynx.  I have a trace I'll
include which will detail the problem.  The problem is when you try to ftp
into an MVS ftp server.  Lynx tries to decode the URL line:
lynx http://username:address@hidden/blahlbah.blah.com
by sending a CWD / 
to change the directory to the "root" directory, then start sending CWD's
for each subdirectory after that.
Unfortunatly, MVS doesn't like the CWD / command, because MVS doesn't handle
directories like that.  Instead it should send several CWD .. commands. 
Hopefully someone there is familure with MVS.  Periods are used as directory
delimiters. So the file HDPN.OR.DOWNLOAD.DART.HSG.G0028V00 can be accessed
by sending 
CWD HDPN
CWD OR
CWD DOWNLOAD
CWD DART
CWD HSG
GET G0028v00

Or you can simply change to the root directory, and
GET HDPN.OR.DOWNLOAD.DARt.HSG.G0028v00

So basically Lynx should recognize when it sends is SYST command to see what
server it is, recognize an MVS server.  Currently Lynx is recognizing it as
a Generic server; which obviously doesn't work.  And then code the ftp line
like this:
ftp://username:address@hidden/../hdpn.or.download.dart.hsg.g00028v00
so it would:
log in
send CWD ..
send GET hdpn.or.download.dart.hsg.g00028v00

And not send a starting CWD / and expect things to work.

Here's the Trace of the failed FTP.

Username field has been replaced with U's and the password fields have been
replaced with P's.

This is with 2-6, since 2-7 doesn't even work.
