       Other environment  variables  are  not  inherited  by  the
       script, unless they are provided via a LYNXCGI_ENVIRONMENT
       statement in the configuration  file.   See  the  lynx.cfg
       file,    and    the    (draft)   CGI   1.1   Specification
       <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The CGI Specification, and other associated documentation,
       should be consulted for general information on CGI  script
       programming.

NATIVE LANGUAGE SUPPORT
</em></a>
       If  configured and installed with Native Language Support,
       Lynx will display status and other messages in your local
       language.  See the file ABOUT_NLS in the source distribution,
       or at your local GNU site, for more information about
       internationalization.

       The following environment variables may be used to alter
       default settings:

       LANG                This variable, if set,  will  override
                           the  default  message language.  It is
                           an ISO 639 two-letter code identifying
                           the  language.  Language codes are NOT
                           the same as the country codes given in
                           ISO 3166.

       LANGUAGE            This  variable,  if set, will override
                           the default message language.  This is a
                           GNU extension that has higher priority for
                           setting the message catalog than LANG or
                           LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These  variables,  if set, specify the
                           notion of native  language  formatting
                           style.  They are POSIXly correct.

       LINGUAS             This variable, if set prior to configuration,
                           limits the installed languages to specific values.
                           It is a space-separated list of two-letter codes.
                           Currently, it is hard-coded to a wish list.

       NLSPATH             This variable, if set, is used as  the
                           path prefix for message catalogs.

    To set your site's NTTP server as the default host for news reading
    and posting via Lynx, set the environment variable NNTPSERVER so that
    it points to its Internet address.  The variable "NNTPSERVER" is used
    to specify the host which will be used as the default for news URLs.

        UNIX
                setenv NNTPSERVER "news.server.dom"

        VMS
                define/system NNTPSERVER "news.server.dom"

    Lynx still supports use of gateway servers, with the servers specified
    via the variables "WWW_access_GATEWAY", where "access" is lower case
    and can be "http", "ftp", "gopher" or "wais".  Most of the gateway
    servers have been discontinued, but "http://www.w3.org:8001" is
    available for wais searches (note that you do not include a
    terminal '/' for gateways, but do for proxies; see below).

    Lynx version 2.2 and beyond supports the use of proxy servers that
    can act as firewall gateways and caching servers.  They are
    preferable to the older gateway servers.  Each protocol used by
    Lynx can be mapped separately using PROTOCOL_proxy environment
    variables of the form:

        UNIX
                setenv http_proxy "http://some.server.dom:port/"
                setenv https_proxy "http://some.server.dom:port/"
                setenv ftp_proxy "http://some.server.dom:port/"
                setenv gopher_proxy "http://some.server.dom:port/"
                setenv news_proxy "http://some.server.dom:port/"
                setenv newspost_proxy "http://some.server.dom:port/"
                setenv newsreply_proxy "http://some.server.dom:port/"
                setenv snews_proxy "http://some.server.dom:port/"
                setenv snewspost_proxy "http://some.server.dom:port/"
                setenv snewsreply_proxy "http://some.server.dom:port/"
                setenv nntp_proxy "http://some.server.dom:port/"
                setenv wais_proxy "http://some.server.dom:port/"
                setenv finger_proxy "http://some.server.dom:port/"
                setenv cso_proxy "http://some.server.dom:port/"

        VMS
                define "http_proxy" "http://some.server.dom:port/"
                define "https_proxy" "http://some.server.dom:port/"
                define "ftp_proxy" "http://some.server.dom:port/"
                define "gopher_proxy" "http://some.server.dom:port/"
                define "news_proxy" "http://some.server.dom:port/"
                define "newspost_proxy" "http://some.server.dom:port/"
                define "newsreply_proxy" "http://some.server.dom:port/"
                define "snews_proxy" "http://some.server.dom:port/"
                define "snewspost_proxy" "http://some.server.dom:port/"
                define "snewsreply_proxy" "http://some.server.dom:port/"
                define "nntp_proxy" "http://some.server.dom:port/"
                define "wais_proxy" "http://some.server.dom:port/"
                define "finger_proxy" "http://some.server.dom:port/"
                define "cso_proxy" "http://some.server.dom:port/"
                (Encase *BOTH* strings in double-quotes to maintain
                 lower case for the PROTOCOL_proxy variable and for
                 the http access type; include /system if you want
                 proxying for all clients on your system.)

    If you wish to override the use of a proxy server for specific hosts or
    entire domains you may use the "no_proxy" environment variable.
    The no_proxy variable can be a comma-separated list of strings defining
    no-proxy zones in the DNS domain name space.  If a tail substring of the
    domain-path for a host matches one of these strings, transactions with that
    node will not be proxied.  Here is an example use of "no_proxy":

        UNIX
                setenv no_proxy "host.domain.dom, domain1.dom, domain2"

        VMS
                define "no_proxy" "host.domain.dom, domain1.dom, domain2"

    You can include a port number in the no_proxy list to override use
    of a proxy server for the host accessed via that port, but not via
    other ports.  For example, if you use "host.domain.dom:119" and/or
    "host.domain.dom:210", then news (port 119) URLs and/or any wais
    (port 210) searches on that host would be excluded, but http, ftp,
    and gopher services (if normally proxied) would still be included,
    as would any news or wais services on other hosts.

    Warning:  Note that setting 'il' as an entry in this list
    will block proxying for the .mil domain as well as the .il domain.
    If the entry is '.il' this will not happen.

    If you wish to override the use of a proxy server completely (i.e.,
    globally override any existing proxy variables), set the value of
    "no_proxy" to "*".  This is the only allowed use of * in no_proxy.

    Note that Lynx treats file URLs on the local host as requests for
    direct access to the file, and does not attempt ftp if that fails.
    It treats both ftp URLs and file URLs on remote hosts as ftp URLs,
    and does not attempt direct file access for either.  If ftp URLs are
    being proxied, file URLs on a remote host will be converted to ftp
    URLs before submission by Lynx to the proxy server, so no special
    procedure for inducing the proxy server to handle them is required.
    Other WWW clients may require that the http server's configuration
    file have "Map file:* ftp:*" in it to perform that conversion.

    If you have not set NNTPSERVER, proxy or no_proxy environment variables
    you can set them at run time via the configuration file lynx.cfg
    (this will not override external settings).

<a name="dos"><em>
Win32 (95/NT) and 386 DOS
</em></a>
  (adapted from "readme.txt" by Wayne Buttles
  and "readme.dos" by Doug Kaufman)

    Here are some environment variables that should be set, usually in a
    batch file that runs the lynx executable. Make sure that you have enough
    room left in your environment. You may need to change your "SHELL="
    setting in config.sys. In addition, lynx looks for a "SHELL" environment
    variable when shelling to DOS.  If  you wish to preserve the environment
    space when shelling, put a line like this in your AUTOEXEC.BAT file also
    "SET SHELL=C:\COMMAND.COM /E:2048". It should match CONFIG.SYS.

    HOME         Where to keep the bookmark file and personal config files.
    TEMP or TMP  Bookmarks are kept here with no HOME.  Temp files here.
    USER         Set to your login name
    LYNX_CFG     Set to the full path and filename for lynx.cfg

    386 version only:
    WATTCP.CFG   Set to the full path for the WATTCP.CFG directory
    (Depending on how you compiled libtcp.a, you may have to use WATCONF.)

    Define these in your batch file for running Lynx.  For example, if your
    application line is "D:\win32\lynx.bat", lynx.bat for Win32 may look like:
        @ECHO OFF
        set home=d:\win32
        set temp=d:\tmp
        set lynx_cfg=d:\win32\lynx.cfg
        d:\win32\lynx.exe %1 %2 %3 %4 %5

    In lynx_386, a typical batch file might look like:

        @echo off
        set HOME=f:/lynx2-8
        set USER=your_login_name
        set LYNX_CFG=%HOME%/lynx.cfg
        set WATTCP.CFG=%HOME%
        f:\lynx2-8\lynx %1 %2 %3 %4 %5 %6 %7 %8 %9

    You will also need to make sure that the WATTCP.CFG file has the
    correct information for IP number, Gateway, Netmask, and Domain Name
    Server. This can also be automated in the batch file.
