There are 17 parts to the distribution of VI written in TPU.  The first,
this file, is a plain text file.  The remainder, are DCL command files.
Files 1-16 should each be executed as DCL procedures in sequence.  Below
is a sequence of steps that should allow you to get VI up and running.

    1)  You should pick a directory to place VI under. Three subdirectories
        will be created during the unpacking process.  They are [.SRC],
        [.EXE], and [.DOC].  The directory names should reveal the purposes of
        these directories.

    2)  Place all 17 of the VI parts into the directory chosen in step 1.
        For each part, 1 through 16, execute each file as a command procedure
        using the command "@<filename>", where <filename> is the name of
        the file to execute (e.g. @VI_001.COM, followed by @VI_002.COM, etc).
        During the execution of VI_016, several diagnostic messages will
        be displayed.  You should only pay attention to the final message
        that says that the section file was either installed properly or
        was not.

NOTE:
        [.SRC]MAKE.COM invokes the $ INSTALL program to REPLACE the
        VI$ROOT:[EXE]VI.GBL file IFF it is already installed.  One possible
        diagnostic message from INSTALL says

%INSTALL-E-OPENIN, error opening VI$ROOT:<EXE>VI.GBL; as input
-RMS-F-DEV, error in device name or inappropriate device type for operation

        and can be ignored since, obviously, there is no such logical name
        defined.

        If you have previously installed VI on your machine, but, VI.GBL is
        not 'installed', then you will get a diagnostic to the effect of

%INSTALL-W-FAIL, failed to DELETE entry for SOME_DEVICE:<SOME_DIRECTORY>VI.GBL
-INSTALL-E-NOKFEFND, Known File Entry not found

        This can also be ignored.

        If you previously installed VI on your machine, and VI.GBL is
        'installed', then this procedure will replace the old one with what
        ever is the latest version of VI.GBL in VI$ROOT:[EXE].  You MUST
        decide whether or not this is what you want to do.  You should EDIT
        [.SRC]MAKE.COM and comment out the INSTALL invocation if desired.

    3)  After executing the VI_016 command file, you should set default to the
        [.SRC] directory, and use the command "$ @make exe,tpusubs" to create
        the VI.EXE executable, and the CALL_USER routines for VI to use.

    4)  Next, set default to [-.DOC] (from the SRC directory), and execute
        the command "$ @VIDOC", and "$ @VIDOC HELP" to create a printable
        version of the current documentation, as well as a HELP file
        that VI can use.  When asked the question:

            Name of library to install HELP files in?

        you should probably answer, VI, unless you really desire to put the
        help file into a library in another directory.  VI.TPU contains the
        path VI$ROOT:[DOC]VI.HLB as the place where it will work from, so if
        you do not place the help file in this library (It will automatically
        be created for you), then you must edit VI.TPU to contain the proper
        path.

    5)  Here you have a decision to make.  I have written an interface to
        callable TPU, [-.SRC]VI.MAR.  If you wish to use this interface,
        then there must be a CLD definition for it installed in DCLTABLES.
        This is really only necessary for using VI as a SUB-process, but
        I find it convienent to install the CLD so that I do not have
        to wait for SET COMMAND to complete when I log in.  If do not
        wish to use the callable TPU interface then go to the next step NOW,
        otherwise hang tight.

        The CLD definition that needs to be installed is in [-.EXE]VI.CLD.  If
        you do not have sufficient privileges to install a new DCLTABLES you
        should get prepared to do so, or find someone that will do it for you
        (now is not entirely necessary, as you can skip to step 6, and do this
        later).

        a)  Take the time to examine the CLD, and make sure it is ok for
            your installation.  If you are on a cluster, then there is
            some extra work that I won't describe here since I have never
            done it.  Basically you need to do the following set of commands.
            (the dollar signs are provide by DCL in case it wasn't obvious).

            $ SET COMMAND [-.EXE]VI.CLD/TABLE=SYS$SHARE:DCLTABLES.EXE/OUT=-
            _$ SYS$SHARE:DCLTABLES.EXE
            $ MCR INSTALL
            INSTALL>SYS$SHARE:DCLTABLES/REPLACE
            INSTALL>EXIT

        b)  This should be all that single CPU sites need to do.  If you
            have a different arrangement at your sight that requires
            something different, then you would know that better than I.
            Remeber that you MUST logout and log back in to have the updated
            DCLTABLES available to your process.  Step 8, below, can not be
            done unless you either 1) do not do (c) below, or 2) you logout and
            log back in after reinstalling DCLTABLES.

        c)  [-.EXE]VI.COM, and [-.EXE]VISETUP.COM contain uses of the symbol,
            "VI".  This symbol is normally equated to "EDIT/TPU".  Once you
            have made the changes necessary to update DCLTABLES, then these
            references should be changed.  In [-.EXE]VI.COM, change VI to
            be "VI", instead of "EDIT/TPU".  In [-.EXE]VISETUP.COM, delete
            the assignment to the variable VI, as the comment there says
            to.

    6)  Next, set default to [-.EXE] (from [.DOC]), and edit the file
        VISETUP.COM.  This file must be executed by each user wishing to
        use VI before they can use it.  You should change the definition of
        VI$ROOT to be the parent directory of the directory you are in NOW.
        E.g. if you are in the directory DUA0:[PUBLIC.VI.DOC], then VI$ROOT
        should be defined to be DUA0:[PUBLIC.VI.].  Note that this file
        potentially defines 3 symbols.  VI allows normal use of VI, VIS
        allows use of the VI.COM procedure to run VI in a subprocess, and
        VIEW allows READONLY editing of a file (as in UNIX).

    7)  The command file VI.COM is used to envoke VI in a sub-process
        so that a minimal amount of overhead for image activation will
        be incurred by the system.  In the VI.COM that you have, there
        are invocations of a SUSPEND, and a RESUME command.  I use these
        commands to suspend kept editors while they are not it use so that
        they will be swapped out or trimmed by the SWAPPER in a more timely
        manner.  This will allow their memory to be put to use by other
        processes whenever possible.  If you do not wish to do this and/or
        do not have these facilities available to you, then you should comment
        out these command lines.

        You may substitute the use of SET PROC/SUSPEND and SET PROC/RESUME
        for these commands.  See the DCL manual or HELP for usage.

    8)  Next, you should be ready to give VI a trial run.  Execute the
        VISETUP.COM procedure in [.EXE].  Then type VI, and hit return.
        You should be off and running.
