    ==============================================================================

    1. Getting started					*vms-started*

    Vim (Vi IMproved) is a vi-compatible text editor that runs on nearly every
    operating system known to humanity.  Now use Vim on OpenVMS too, in character
    or X/Motif environment.  It is fully featured and absolutely compatible with
    Vim on other operating systems.

    ==============================================================================

    2. Download files					*vms-download*

    You can download the Vim source code by ftp from the official Vim site:
    	ftp://ftp.vim.org/pub/vim/
    Or use one of the mirrors:
    	ftp://ftp.vim.org/pub/vim/MIRRORS

    You will need both the Unix and Extra archives to build vim.exe for VMS.
    For using Vim's full power you will need the runtime files as well.

    You can download precompiled executables from:
    	http://www.polarhome.com/vim/
    	ftp://ftp.polarhome.com/pub/vim/

    To use the precompiled binary version, you need one of these archives:

      vim-XX-exe-ia64-gui.zip       IA64 GUI/Motif executables
      vim-XX-exe-ia64-gtk.zip       IA64 GUI/GTK executables
      vim-XX-exe-ia64-term.zip      IA64 console executables
      vim-XX-exe-axp-gui.zip	Alpha GUI/Motif executables
      vim-XX-exe-axp-gtk.zip	Alpha GUI/GTK executables
      vim-XX-exe-axp-term.zip       Alpha console executables
      vim-XX-exe-vax-gui.zip	VAX GUI executables
      vim-XX-exe-vax-term.zip       VAX console executables

    and of course (optional)
      vim-XX-runtime.zip		runtime files

    The binary archives contain: vim.exe, ctags.exe, xxd.exe files.

    For GTK executables you will need GTKLIB that is available for
    Alpha and IA64 platform.

    ==============================================================================

    3. Compiling						*vms-compiling*

    See the file [.SRC]INSTALLVMS.TXT.

    ==============================================================================

    4. Problems						*vms-problems*

    The code has been tested under Open VMS 6.2 - 8.2 on Alpha, VAX and IA64
    platforms with the DEC C compiler.  It should work without bigger problems.
    If your system does not have some include libraries you can tune up in
    OS_VMS_CONF.H file.

    If you decided to build Vim with +perl, +python, etc. options, first you need
    to download OpenVMS distributions of Perl and Python.  Build and deploy the
    libraries and change adequate lines in MAKE_VMS.MMS file.  There should not be
    a problem from Vim side.

    Also GTK, XPM library paths should be configured in MAKE_VMS.MMS

    Note: Under VAX it should work with the DEC C compiler without problems.  The
    VAX C compiler is not fully ANSI C compatible in pre-processor directives
    semantics, therefore you have to use a converter program what will do the lion
    part of the job.  For detailed instructions read file INSTALLvms.txt

    MMS_VIM.EXE is build together with VIM.EXE, but for XD.EXE you should
    change to subdirectory and build it separately.

    CTAGS is not part of the Vim source distribution anymore, however the OpenVMS
    specific source might contain CTAGS source files as described above.
    You can find more information about CTAGS on VMS at
    	http://www.polarhome.com/ctags/

    Advanced users may try some acrobatics in FEATURE.H file also.

    It is possible to compile with +xfontset +xim options too, but then you have
    to set up GUI fonts etc. correctly.  See :help xim from Vim command prompt.

    You may want to use GUI with GTK icons, then you have to download and install
    GTK for OpenVMS or at least runtime shareable images - LIBGTK from
    polarhome.com

    For more advanced questions, please send your problem to Vim on VMS mailing
    list <vim-vms@polarhome.com>
    More about the vim-vms list can be found at:
    	http://www.polarhome.com/mailman/listinfo/vim-vms

    ==============================================================================

    5. Deploy						*vms-deploy*

    Vim uses a special directory structure to hold the document and runtime files:

       vim (or wherever)
        |- tmp
        |- vim57
        |----- doc
        |----- syntax
        |- vim62
        |----- doc
        |----- syntax
        |- vim64
        |----- doc
        |----- syntax
        vimrc    (system rc files)
        gvimrc

    Use:

    	define/nolog VIM	device:[path.vim]
    	define/nolog VIMRUNTIME device:[path.vim.vim60]
    	define/nolog TMP	device:[path.tmp]

    to get vim.exe to find its document, filetype, and syntax files, and to
    specify a directory where temporary files will be located.  Copy the "runtime"
    subdirectory of the vim distribution to vimruntime.

    Logicals $VIMRUNTIME and $TMP are optional.

    If $VIMRUNTIME is not set, Vim will guess and try to set up automatically.
    Read more about it at :help runtime

    If $TMP is not set, you will not be able to use some functions as CTAGS,
    XXD, printing etc. that use temporary directory for normal operation.
    The $TMP directory should be readable and writable by the user(s).
    The easiest way to set up $TMP is to define a logical:

    	define/nolog TMP SYS$SCRATCH
    or as:
    	define/nolog TMP SYS$LOGIN

    ==============================================================================

    6. Practical usage					*vms-usage*

    Usually, you want to run just one version of Vim on your system, therefore
    it is enough to dedicate one directory for Vim.
    Copy the whole Vim runtime directory structure to the deployment position.
    Add the following lines to your LOGIN.COM (in SYS$LOGIN directory).
    Set up the logical $VIM as:

    	$ define VIM device:<path>

    Set up some symbols:

    	$ ! vi starts Vim in chr. mode.
    	$ vi*m  :== mcr VIM:VIM.EXE

    	$ !gvi starts Vim in GUI mode.
    	$ gv*im :== spawn/nowait mcr VIM:VIM.EXE -g

    Please, check the notes for customization and configuration of symbols.

    You may want to create .vimrc and .gvimrc files in your home directory
    (SYS$LOGIN) to overwrite default settings.

    The easiest way is just rename example files.  You may leave the menu file
    (MENU.VIM) and files vimrc and gvimrc in the original $VIM directory.  It will
    be default setup for all users, and for users it is enough just to have their
    own additions or resetting in their home directory in files .vimrc and .gvimrc.
    It should work without problems.

    Note: Remember, system rc files (default for all users) don't have a leading
    ".".  So, system rc files are:

    	$VIM:vimrc
    	$VIM:gvimrc
    	$VIM:menu.vim

    and user customized rc files are:

    	sys$login:.vimrc
    	sys$login:.gvimrc

    You can check that everything is on the right place with the :version command.

    Example LOGIN.COM:

    	$ define/nolog VIM RF10:[UTIL.VIM]
    	$ vi*m :== mcr VIM:VIM.EXE
    	$ gv*im:== spawn/nowait/input=NLA0 mcr VIM:VIM.EXE -g -GEOMETRY 80x40
    	$ set disp/create/node=192.168.5.223/trans=tcpip

    Note: This set-up should be enough, if you are working on standalone server or
    clustered environment, but if you want to use Vim as internode editor in
    DECNET environment, it will satisfy as well.
    You just have to define the "whole" path:

    	$ define VIM "<server_name>[""user password""]::device:<path>"
    	$ vi*m :== "mcr VIM:VIM.EXE"

    as for example:

    	$ define VIM "PLUTO::RF10:[UTIL.VIM]"
    	$ define VIM "PLUTO""ZAY mypass""::RF10:[UTIL.VIM]" ! if passwd required

    You can also use the $VIMRUNTIME logical to point to the proper version of Vim
    if you have installed more versions at the same time.  If $VIMRUNTIME is not
    defined Vim will borrow its value from the $VIM logical.  You can find more
    information about the $VIMRUNTIME logical by typing :help runtime as a Vim
    command.

    System administrators might want to set up a system wide Vim installation,
    then add to the SYS$STARTUP:SYLOGICALS.COM

    	$ define/nolog/sys VIM device:<path>
    	$ define/nolog/sys TMP SYS$SCRATCH

    and to the SYS$STARTUP:SYLOGIN.COM

    	$ vi*m :== mcr VIM:VIM.EXE
    	$ gv*im:== spawn/nowait/input=NLA0 mcr VIM:VIM.EXE -g -GEOMETRY 80x40

    It will set up a normal Vim work environment for every user on the system.

    IMPORTANT: Vim on OpenVMS (and on other case insensitive system) command line
    parameters are assumed to be lowecase. In order to indicate that a command
    line parameter is uppercase "/" sign must be used.

    Examples:

    	vim -R  filename  ! means: -r List swap files and exit
    	vim -/r filename  ! means: -R Readonly mode (like "view")
    	vim -u	<vimrc>   ! means: -u Use <vimrc> instead of any .vimrc
    	vim -/u <gvimrc>  ! means: -U Use <gvimrc> instead of any .gvimrc

    ==============================================================================

    7. GUI mode questions					*vms-gui*

    OpenVMS is a real mainframe OS, therefore even if it has a GUI console, most
    of the users do not use a native X/Window environment during normal operation.
    It is not possible to start Vim in GUI mode "just like that".  But anyhow it
    is not too complicated either.

    First of all: you will need an executable that is built with the GUI enabled.

    Second: you need to have installed DECW/Motif on your VMS server, otherwise
    you will get errors that some shareable libraries are missing.

    Third: If you choose to run Vim with extra features such as GUI/GTK then you
    need a GTK installation too or at least a GTK runtime environment (LIBGTK
     can be downloaded from	http://www.polarhome.com/vim/.

    1) If you are working on the VMS X/Motif console:
       Start Vim with the command:

    	$ mc device:<path>VIM.EXE -g

       or type :gui as a command to the Vim command prompt.  For more info :help
       gui

    2) If you are working on some other X/Window environment like Unix or a remote
       X VMS console.  Set up display to your host with:

    	$ set disp/create/node=<your IP address>/trans=<transport-name>

       and start Vim as in point 1.  You can find more help in VMS documentation or
       type: help set disp in VMS prompt.
       Examples:

    	$ set disp/create/node=192.168.5.159		 ! default trans is DECnet
    	$ set disp/create/node=192.168.5.159/trans=tcpip ! TCP/IP network
    	$ set disp/create/node=192.168.5.159/trans=local ! display on the same node

    Note: you should define just one of these.
    For more information type $help set disp in VMS prompt.

    3) Another elegant solution is XDM if you have installed on OpenVMS box.
       It is possible to work from XDM client as from GUI console.

    4) If you are working on MS-Windows or some other non X/Window environment
       you need to set up one X server and run Vim as in point 2.
       For MS-Windows there are available free X servers as MIX , Omni X etc.,
       as well as excellent commercial products as eXcursion or ReflectionX with
       built-in DEC support.

    Please note, that executables without GUI are slightly faster during startup
    then with enabled GUI in character mode. Therefore, if you do not use GUI
    features, it is worth to choose non GUI executables.

    8.1 backspace/delete

    There are backspace/delete key inconsistencies with VMS.
    :fixdel doesn't do the trick, but the solution is:

    	:inoremap ^? ^H		" for terminal mode
    	:inoremap <Del> ^H	" for gui mode

    Read more in ch: 8.6 (Terminal problems).
    (Bruce Hunsaker <BNHunsaker@chq.byu.edu> Vim 5.3)

    8.2 Filters

    Vim supports filters, i.e., if you have a sort program that can handle
    input/output redirection like Unix (<infile >outfile), you could use

    	:map \s 0!'aqsort<CR>

    (Charles E. Campbell, Jr. <cec@gryphon.gsfc.nasa.gov> Vim 5.4)

    8.3 VMS file version numbers

    Vim is saving files into a new file with the next higher file version
    number, try these settings.

    	:set nobackup	     " does not create *.*_ backup files
    	:set nowritebackup   " does not have any purpose on VMS.  It's the
    			     " default.

    Recovery is working perfect as well from the default swap file.
    Read more with :help swapfile

    (Claude Marinier <ClaudeMarinier@xwavesolutions.com> Vim 5.5, Zoltan Arpadffy
    Vim 5.6)

    8.4 Directory conversion

    Vim will internally convert any unix-style paths and even mixed unix/VMS
    paths into VMS style paths.  Some typical conversions resemble:

    	/abc/def/ghi		-> abc:[def]ghi.
    	/abc/def/ghi.j		-> abc:[def]ghi.j
    	/abc/def/ghi.j;2	-> abc:[def]ghi.j;2
    	/abc/def/ghi/jkl/mno	-> abc:[def.ghi.jkl]mno.
    	abc:[def.ghi]jkl/mno	-> abc:[def.ghi.jkl]mno.
    	  ./			-> current directory
    	  ../			-> relative parent directory
    	  [.def.ghi]		-> relative child directory
    	   ./def/ghi		-> relative child directory

    Note: You may use <,> brackets as well (device:<path>file.ext;version) as
    rf10:<user.zay.work>test.c;1

    (David Elins <delins@foliage.com>, Jerome Lauret
    <JLAURET@mail.chem.sunysb.edu> Vim 5.6 )

    8.5 Remote host invocation

    It is possible to use Vim as an internode editor.
    1. Edit some file from remote node:

    	vi "<server>""username passwd""::<device>:<path><filename>;<version>"

    example:
    	vi "pluto""zay passwd""::RF10:<USER.ZAY.WORK>TEST.C;1"

    Note: syntax is very important, otherwise VMS will recognize more parameters
    instead of one (resulting with: file not found)

    2.  Set up Vim as your internode editor.  If Vim is not installed on your
    host, just set up your IP address, the full Vim path including the server name
    and run the command procedure below:

    	$ if (p1 .eqs. "") .OR. (p2 .eqs. "") then goto usage
    	$ set disp/create/node=<your_IP_here>/trans=tcpip
    	$ define "VIM "<vim_server>""''p1' ''p2'""::<device>:<vim_path>"
    	$  vi*m :== "mcr VIM:VIM.EXE"
    	$ gv*im :== "spawn/nowait mcr VIM:VIM.EXE -g"
    	$ goto end
    	$ usage:
    	$ write sys$output " Please enter username and password as a parameter."
    	$ write sys$output " Example: @SETVIM.COM username passwd"
    	$ end:

    Note: Never use it in a clustered environment (you do not need it), loading
    could be very-very slow, but even faster then a local Emacs. :-)

    (Zoltan Arpadffy, Vim 5.6)

    8.6 Terminal problems

    If your terminal name is not known to Vim and it is trying to find the default
    one you will get the following message during start-up:
    Terminal entry not found in termcap
    'unknown-terminal' not known.  Available built-in terminals are:
        builtin_gui
        builtin_riscos
        builtin_amiga
        builtin_beos-ansi
        builtin_ansi
        builtin_vt320
        builtin_vt52
        builtin_pcansi
        builtin_win32
        builtin_xterm
        builtin_iris-ansi
        builtin_debug
        builtin_dumb
    defaulting to 'vt320'
    The solution is to define default terminal name:

    	$ ! unknown terminal name.  Let us use vt320 or ansi instead.
    	$ ! Note: it's case sensitive
    	$ define term "vt320"

    Terminals from VT100 to VT320 (as V300, VT220, VT200 ) do not need any extra
    keyboard mappings.  They should work perfect as they are, including arrows,
    Ins, Del buttons etc., except Backspace in GUI mode.  To solve it, add to
    .gvimrc:

    	inoremap <Del> <BS>

    Vim will also recognize that they are fast terminals.

    If you have some annoying line jumping on the screen between windows add to
    your .vimrc file:

    	set ttyfast	" set fast terminal

    Note: if you're using Vim on remote host or through very slow connection, it's
    recommended to avoid fast terminal option with:

    	set nottyfast   " set terminal to slow mode

    (Zoltan Arpadffy, Vim 5.6)

    8.7 Hex-editing and other external tools

    A very important difference between OpenVMS and other systems is that VMS uses
    special commands to execute executables:

    	RUN <path>filename
    	MCR <path>filename <parameters>

    OpenVMS users always have to be aware that the Vim command :! "just" drop them
    to DCL prompt.  This feature is possible to use without any problem with all
    DCL commands, but if we want to execute some program as XXD, CTAGS, JTAGS etc.
    we're running into trouble if we follow the Vim documentation (see: help
    xxd).

    Solution: Execute with the MC command and add the full path to the executable.
    Example: Instead of :%!xxd command use:

    	:%!mc vim:xxd

    ... or in general:
    	:!mc <path>filename <parameters>

    Note: You can use XXD and CTAGS from GUI menu.

    To customize ctags it is possible to define the logical $CTAGS with standard
    parameters as:

    	define/nolog CTAGS "--totals -o sys$login:tags"

    For additional information, please read :help tagsearch and CTAGS
     documentation at	http://ctags.sourceforge.net/ctags.html.

    (Zoltan Arpadffy, Vim 5.6-70)

    8.8 Sourcing vimrc and gvimrc

    If you want to use your .vimrc and .gvimrc from other platforms (e.g. Windows)
    you can get in trouble if you ftp that file(s): VMS has different end-of-line
    indication.
    The symptom is that Vim is not sourcing your .vimrc/.gvimrc, even if you say:

    	:so sys$login:.vimrc

    One trick is to compress (e.g. zip) the files on the other platform and
    uncompress it on VMS; if you have the same symptom, try to create the files
    with copy-paste (for this you need both op. systems reachable from one
    machine, e.g. an Xterm on Windows or telnet to Windows from VMS).

    (Sandor Kopanyi, <sandor.kopanyi@mailbox.hu> Vim 6.0a)

    8.9 Printing from Vim

    To be able to print from Vim (running in GUI mode) under VMS you have to set
    up $TMP logical which should point to some temporary directory and logical
    SYS$PRINT to your default print queue.
    Example:

    	$define SYS$PRINT HP5ANSI

    You can print out whole buffer or just the marked area.
    More info under :help hardcopy

    (Zoltan Arpadffy, Vim 6.0c)

    8.10 Setting up the symbols

    When I use GVIM this way and press CTRL-Y in the parent terminal, gvim exits.
    I now use a different symbol that seems to work OK and fixes the problem.
    I suggest this instead:

    	$ GV*IM:==SPAWN/NOWAIT/INPUT=NLA0: MCR VIM:VIM.EXE -G -GEOMETRY 80X40

    The /INPUT=NLA0: separates the standard input of the gvim process from the
    parent terminal, to block signals from the parent window.
    Without the -GEOMETRY, the GVIM window size will be minimal and the menu
    will be confused after a window-resize.

    (Carlo Mekenkamp, Coen Engelbarts, Vim 6.0ac)

    8.11 diff and other GNU programs

    From 6.0 diff functionality has been implemented, but OpenVMS does not use
    GNU/Unix like diff therefore built in diff does not work.
    There is a simple solution to solve this anomaly.  Install a Unix like diff
    and Vim will work perfect in diff mode too.  You just have to redefine your
    diff program as:

    	define /nolog diff <GNU_PATH>diff.exe

    Another, more sophisticated solution is described below (8.12 diff-mode)
    There are some other programs as patch, make etc that may cause same problems.
    At www.polarhome.com is possible to download an GNU package for Alpha and VAX
    boxes that is meant to solve GNU problems on OpenVMS.
    ( Zoltan Arpadffy, Vim 6.1)

    8.12 diff-mode

    Vim 6.0 and higher supports vim diff-mode (See |new-diff-mode|, |diff-mode|
    and |08.7|).  This uses the external program 'diff' and expects a Unix-like
    output format from diff.  The standard VMS diff has a different output
    format.  To use vim on VMS in diff-mode, you need to:
        1 Install a Unix-like diff program, e.g. GNU diff
        2 Tell vim to use the Unix-like diff for diff-mode.

    You can download GNU diff from the VIM-VMS website, it is one of the GNU
     tools in	http://www.polarhome.com/vim/files/gnu_tools.zip. I suggest to
    unpack it in a separate directory "GNU" and create a logical GNU: that
    points to that directory, e.g:

       DEFINE GNU    <DISK>:[<DIRECTORY>.BIN.GNU]

    You may also want to define a symbol GDIFF, to use the GNU diff from the DCL
    prompt:

       GDIFF :==     $GNU:DIFF.EXE

    Now you need to tell vim to use the new diff program.  Take the example
    settings from |diff-diffexpr| and change the call to the external diff
    program to the new diff on VMS.  Add this to your .vimrc file:

         " Set up vimdiff options
           if v:version >= 600
    	" Use GNU diff on VMS
    	set diffexpr=MyDiff()
    	function MyDiff()
    	   let opt = ""
    	   if &diffopt =~ "icase"
    	     let opt = opt . "-i "
    	   endif
    	   if &diffopt =~ "iwhite"
    	     let opt = opt . "-b "
    	   endif
    	   silent execute "!mc GNU:diff.exe -a " . opt . v:fname_in . " " .  v:fname_new .
    		\  " > " . v:fname_out
    	endfunction
          endif

    You can now use vim in diff-mode, e.g. to compare two files in read-only
    mode:

        $ VIM -D/R <FILE1> <FILE2>

    You can also define new symbols for vimdiff, e.g.:

        $ VIMDIFF     :== 'VIM' -D/R
        $ GVIMDIFF    :== 'GVIM' -D/R

    You can now compare files in 4 ways:

        1. VMS  diff:  $ DIFF     <FILE1> <FILE2>
        2. GNU  diff:  $ GDIFF    <FILE1> <FILE2>
        3. VIM  diff:  $ VIMDIFF  <FILE1> <FILE2>
        4. GVIM diff:  $ GVIMDIFF <FILE1> <FILE2>

    ( Coen Engelbarts, Vim 6.1)

    8.13 Allow '$' in C keywords

    DEC C uses many identifiers with '$' in them.  This is not allowed in ANSI C,
    and vim recognises the '$' as the end of the identifier.  You can change this
    with the YXXYiskeyword|command.
    Add this command to your .vimrc file:

        autocmd FileType c,cpp,cs  set iskeyword+=$

    You can also create the file(s) $VIM/FTPLUGIN/C.VIM (and/or CPP.VIM and
    CS.VIM) and add this command:

    	set iskeyword+=$

    Now word-based commands, e.g. the '*'-search-command and the CTRL-]
    tag-lookup, work on the whole identifier.  (Ctags on VMS also supports '$' in
    C keywords since ctags version 5.1.)

    ( Coen Engelbarts, Vim 6.1)

    8.14 VIMTUTOR for beginners

    It exits VIMTUTOR.COM DCL script that can help Vim beginners to learn/make
    first steps with Vim on OpenVMS.  Depending of binary distribution you may
    start it with:

    	@vim:vimtutor
