LYNX-DEV Building and using Lynx with DECNET emulation |

I've been working in the group that has put out the OpenVMS Internet
Product Suite CD. Lynx is one of the freeware browsers included on that
CD. A customer asked about running Lynx for strictly local access in
viewing html file, to be run on a system with no TCP/IP package.
My work with Lynx has been mainly in verifying builds and packaging, but
I did take a look and tried the /macro=(dec_c=1,decnet=1) option
documented for a build with socket emulation over DECnet. After making a
few changes I got an image for Alpha (DEC C V5.2-001) which builds and
views local files, does not do any network access. Have not tried VAX
build yet.
Appended at end is list of files changes + differences. If this work is
of use to VMS Lynx community I can clean it up a bit and post files.
Obviously to do a more careful job will take more time, which I don't
have right now; in the meantime any input on the questions below will
help. Did not find answers yet in a quick scan of Lynx help and of mail
(current messages, not any archives). These questions go beyond what
the customer asked about:
- Are any changes below avoidable? Any more elegant want to do them?
- Any pointers appreciated on syntax for standard build, and also the
one with DECNET emulation. I experimented with remote file access with
file:// and ftp:// on lynx built for UCX and also DECNET version,
using both standard and DECNET syntax. (Assume file:// is intended
for local only, wanted to try various options.) I'm having trouble
getting to remote hosts, but the problem may be with proxy.
In [.vms]descrip.mms saw the note about removing FTP, Gopher, News,
WAIS, so assume HTML view access might be main option I'd be
interested in.
Thanks,
