    Type "DV" to start the DASD Vision control program.

        DASD Vision - as the name implies, this program allows one to
                'see' a disk drive as it really exists.  ANY drive that
                is organized in standard DOS format can be processed,
                and ALL files (hidden, system, etc.) are displayed.
                The first 'file' is the Volume Label of the disk,
                followed by sub-directories, then the files (all in
                alphabetical order by section).

                Press F1 key after startup for Help information.

                Hold down the ALT key then press any Letter key (from
                A to Z) to select a different drive.

                Use the cursor keys to highlight any directory name,
                then press ENTER to switch to the selected sub-dir.

                Use cursor keys to highlight any file name then type
                any DOS command line, using "==" (two equal signs) for
                the file name to execute programs or procedures against
                the selected file.  Just press ENTER to execute the
                AUTO command against the currently highlighted file.
                See bottom section of screen for the current Auto
                command or use the INSERT key to change this command.
                Edit/Modify the DV.BAT file to change the command default
                passed to DV386 on startup (usually 'Edit').

                Press the F4 key to Display the file, or press the F8 key
                to Execute the file (must be type .BAT, .COM or .EXE).

                Press ALT + F1 to access the Note Pad system.  Use
                ALT plus ARROW keys to Scroll thru Pads ( A-Z, 0-9 ).
                Editing is allowed, and changes are saved automatically
                after exit ( unless ALT+ESC is used to Exit ).

                If you are running Version 3.x ( vice 2.0.B ) press
                F2 to Return to the ROOT directory, F10 to Sort files
                Alphabetically by NAME and Extension, F11 to Sort by
                DATE ( Latest files First ), or F12 to Sort by SIZE
                ( Largest files First ).  DV386 returns to File NAME
                Sort when re-started ( unless ALT+F3 or ALT+ESC was
                last used to exit ).

                Total Bytes reported in Version 3.0.C has been changed from
                Hex to Decimal format ( Base 10 vice Base 16 ).  When working
                with actual RAM Addresses, bytes are accessed in blocks of
                1,024 bytes.  DV386 reports 1k as 1,000 bytes ( vice 1k =
                1024 ) and 1 Meg as 1,000,000 bytes ( vice 1,048,576 ).
                This should reflect a more accurate picture of REAL bytes.


        * Notes :      Optimum performance using RAMDisk for EXE/BAT
                         and Work files.  Mod DV.BAT if other Drive(s)
                         are used (All lines with %R% to d:).  Must also
                         place DV386.EXE on RAMDrive! (DASD Vision will
                         automatically place C:\DOS\COMMAND.COM on the
                         work/temp disk (defaults to C:\ Root).

                         DOS program COMMAND.COM MUST be accessible
                         in the ROOT of the SysWk Drive ( See file
                         Autoexec.Bat & DV.Bat, All %R% lines), or
                         DASD Vision will NOT work.  The program will
                         be copied automatically, if possible, from
                         C:\DOS ... if Copy fails, DV386 Calls will
                         result in 'File not found' errors for ANY/ALL
                         DOS Commands and/or Programs by DV386.  The
                         SysWk Drive is used for relocating DASD Vision
                         System Programs & Files, Work Files and
                         COMMAND.COM ... NotePad files go to C:\DOS\DV3 ,
                         option files PAGEWITE/CRTCFLAG.DV3 go to C:\
                         (Root) and the DV3DUMP file is created on the
                         Current Drive, in the Current Sub-directory.

                         If excessive flashing of the Video screen is a
                         problem with the CRCTFLAG.DV3 file (30 line
                         mode) then add the TRANSPAR.DV3 file to the
                         Root directory.  This will run 30 Line Mode
                         AND Transparency together.  ALL System files
                         ending in .DV3 are used as Flags and actual
                         file content is unimportant (comment/remark).



    Type "CRY fs" to start the Cipher program on file 'fs'.

        DCSS (Data Cryptographic Security System) is a Data Encryption/
                Decryption program used to secure sensitive data files
                or programs against unauthorized access.

                The CRY and/or CRYPTO procedures assume the file to be
                processed is in the current directory.  To process a
                file outside the current sub-dir, type "CRY fs1 fs2",
                where fs1 is the Drive and/or Path where the file is
                located, and fs2 is the name of the file itself.
                (i.e. "CRY C:\TEXT MYFILE")  The procedure will change
                to sub-dir 'fs1', process file 'fs2' then return.

                The CRYPTO12.EXE main program will automatically Cipher
                (Encode or Decode) the specified file after prompting
                for the Data Set Cipher Key that one must supply for
                each file.  The program will recognize an encoded file 
                and will decode it automatically.  A ciphered file will
                appear as 'garbage' and only the correct program along
                with the proper key can restore the data to its original
                format.

                The Data Set Cipher 'key' is string of letters, numbers
                and special characters up to 32 characters long.  The
                longer the key, the better the security, and from 4 to
                16 characters is average for this purpose.  Do NOT
                forget any key used to cipher a file, as it is NOT
                stored anywhere after use by the program!

                If a file is decoded using an incorrect Cipher key, AND
                the EXACT incorrect key is known, the file can be recovered
                by running CRYPTO a SECOND time with the INCORRECT key
                to Encode the file back to its original state, then AGAIN
                using the CORRECT key to Decode the file to a readable
                state.  If the exact nature of the error is unknown, then
                the file must be restored from a backup set, or deleted,
                as it is unusable.

                Ciphered files are NOT compatible with any other program
                and can NOT be Decoded on any other system, without your
                special version of this program.  If you have a need to
                distribute ciphered files, be sure and use the CRYNONE
                program.  The program itself will also have to be
                distributed along with the encoded file(s), and of course
                the Cipher key.  One can create a special version of
                CRYPTO.BAT that calls the CRYNONE program for this purpose.

        Note:   See file CRYPTO.DOC for additional information.



    Type "PATCH fs" to modify program and/or other non-text files.

        Data is changed by entering bytes in Hexadecimal format at the
        current cursor location (highlighted in reverse video).  It is
        assumed that anyone using this program is familiar with binary
        formatted data as well as hexadecimal formats.  Changed data is
        written back to disk automatically after scrolling to another
        block of data or exiting the program.

        Displayed blocks are formatted at 256 bytes each, with the Block
        number in Decimal (starting with Block 0), the Base and Offset of
        the current byte in Hex and Decimal, and the Data itself in Hex
        and ASCII.  Decimal display of Data is also provided by pressing
        the F1 key, then the ESC key to return to Hexadecimal.

        The relative location of the cursor in a FILE can be calculated
        by multiplying the displayed Block (Blk) number by 256, then adding
        the result to the current row Base value plus the current column
        Offset for the appropriate byte (i.e. [Block * 256] + Base + Offset).


    Type "VIEW fs" to display standard Text files.

        Files with line lengths up to 132 characters can be viewed by
        using "VIEW fs 132".  The View procedure will automatically
        switch to the LIST program if the file size exceeds 64k.



    Type "25", "50", "80" or "132" to change to different Screen formats.

        Procedures and/or programs that change the Line format will
        pass this NEW format when returning to DASD Vision as long as
        30 Line Mode is NOT activated (by CRTCFLAG.DV3 file).


    Type "IML" at any time to force a Hardware restart of the CPU.


    Add "SAVEIT" at the beginning of the AUTOEXEC.BAT procedure to save the
        initial startup screen to disk as file SAVEIT.TXT, or use "SAVEIT fs"
        to specify file 'fs' as appended output (the file will be created
        automatically if not found) for the current screen contents in any
        procedure.


    (All other programs are used by the above for normal operation...)
