- Copyright (C) Vsevolod V. Volkov 1991-1995
-
-
-
- Minimal requirements:
- Computer. . . . . . . . IBM PC or BIOS-compatible
- Operation system. . . . DOS 3.20 or higher
- Free RAM. . . . . . . . about 155 Kb
-
-
- Implementation notes:
- - all file and memory management operations implemented on
- DOS level via Int 21h
- - keyboard polling implemented on BIOS level via Int 16h
- - I/O ports access: only for snow elimination on CGA, only
- port 3DAh and only if this port is detected
-
-
- Some notes and recommendations:
-
- 1. The Volkov Commander allows you to select, copy, move and
- delete directories (including all contained subdirectories)
- as well as ordinary files.
-
- 2. You can split and merge files while copying. What you have
- to do for splitting - if you see following message while
- copying file to diskette:
-
- ╔═════════════ Copy ══════════════╗
- ║ There isn't enough room to copy ║
- ║ filename to ║
- ║ D:\filename ║
- ║ Abort Continue ║
- ╚═════════════════════════════════╝
-
- change diskette and select "Continue". First part of splited
- file will have such date and time as had source file, other
- parts will have current date and time.
-
- How to merge two files? You have to copy second part of
- splitted file to directory where first part resides. You
- will see following message
-
- ╔═════════════════ Copy ══════════════════╗
- ║ The following file exists ║
- ║ D:\filename ║
- ║ Do you wish to write over the old file? ║
- ║ Overwrite All aPpend Skip ║
- ╚═════════════════════════════════════════╝
-
- - choose "Append".
-
- 3. Pressing Alt-F10 after F5 or F6 (Copy or Rename commands)
- pops up panel with directory tree of drive, specified in
- destination path - you can choose then right place to copy
- to. Pressing F10 invoke directory tree of current (source)
- disk.
-
- 4. Group Selection (Grey +) and Group Inversion (Grey *) acts
- upon files only, while Unselection (Grey -) acts on both
- files and directories.
-
- 5. After completion of operation upon selected group of files
- you can restore selection using Restore Selection (^M)
- command.
-
- 6. You can specify a name of DOS command, executable or batch
- file in command line as a parameter for VC which will be
- executed automatically when the Volkov Commander starts. For
- example:
-
- VC startup.bat
-
- VC will start up and then run batch file startup.bat, which
- may contain DOS commands and resident programs.
-
- 7. There are two options of residing VC in RAM:
-
- 1. "Small" mode - The Commander deallocates memory before
- execution of each DOS command or application. When
- program started from VC is terminated, file VC.COM is
- reloaded from path it was originally started. In this
- mode only about 12.5 Kbytes of The Commander resides in
- memory when programs run.
-
- 2. Full-resident mode - VC is totally allocated in the RAM
- (about 76 Kb). While in full-resident mode, executable
- file VC.COM is loaded only once and does not need later.
- This mode is faster.
-
- Small mode is selected if 'Memory Allocation' option checked
- in pull-down menu Options. It is possible while being in one
- of this modes to launch applications in opposite execution
- mode without using menu: you just have to press Shift-Enter
- instead of Enter. The status of Shift key is also examined
- when starting programs from User Menu (F2) or History
- (Alt-F8).
-
- Mode choice recommendations:
-
- 1. If you have more than 65 Kbytes of high memory (UMB)
- free - it would be preferable to load VC into UMB using
- command LH VC under MS-DOS 5.0, HILOAD VC under DR-DOS
- 6.0. In such case it would be better to utilize "maximal
- mode" for faster operating.
-
- 2. If you have no UMBs in your system or UMB size is
- insufficient - "small mode" will be optimal if you run VC
- from hard disk. If you have RAM-disk it will be even
- better to copy VC.COM to RAM-disk and start from it. For
- example, it could be done in such a way:
-
- COPY C:\VC\vc.com E:\
- SET VC=C:\VC
- E:\vc
-
- SET VC=... command specifies directory where VC.INI,
- VC.HLP, main menu VC.MNU, etc reside. If VC environment
- variable is not specified, these files are looked for in
- directory VC.COM was started from.
-
- 3. If you run VC from floppy disk - "maximal mode" will be
- the best choice. In spite of expense of RAM, this choice
- save you from painful waiting for VC.COM reloading after
- return from applications.
-
- 8. You can compress VC.COM by almost any executable packing
- program, such as DIET, LZEXE or PKLITE. Some packers (for
- example, LZEXE) support only EXE-files. Older versions of
- PKLITE or DIET before v1.44 refusing to pack COM-files of
- size near 64K. In such cases you'll have to transform VC.COM
- to EXE-format using COM2EXE utility.
-
- 9. Two methods of launching DOS commands and applications from
- VC is available.
-
- First - standard way: executing COMMAND.COM /C <command>. In
- this case it is needed that COMSPEC variable in DOS
- environment shall be installed properly and presence of
- command processor on mentioned path. This is no-risky way
- (and used by default).
-
- Second method - using DOS interrupt int 2Eh - may not work
- in some cases (for example 4DOS and NDOS support this method
- optionally, OS/2 DOS box does not support it at all). This
- method have some advantages over the standard method: you
- are able to modify master DOS environment variables by
- usual SET, PATH, PROMPT etc. commands, second copy of shell
- (COMMAND.COM or replacement) wouldn't be loaded into memory,
- therefore commands and applications are executed faster and
- after loading of resident programs there is no "hole" in RAM
- after second copy of COMMAND.COM. There are also some
- shortcomings inherited in DOS: BATCH-file interruption with
- Ctrl-Break stops execution but with trying to execute next
- command, continued execution of interrupted batch file and
- then ordered command; DOS has no possibility of nested
- execution through int 2Eh, so if one program started with
- int 2Eh and then started another one through int 2Eh also,
- the control will be given to the process which started first
- program and other program is allocated in RAM, though there
- is no access to it. Shortly speaking - the choice is yours.
- You can select second method by checking "Quick execute
- commands" in Advanced options.
-
- 10. "Memory Info" (Alt-F5) command gives you useful information
- about programs loaded into low (first 640 Kbyte) and upper
- (UMB area) memory: PSP segment address, number and size of
- memory blocks occupied by program, and intercepted interrupt
- vectors. You can also remove from memory thouse resident
- programs which were loaded after the Commander.
-
- You can select/unselect programs from the list using Insert,
- Grey -, Grey + keys and then remove selected programs from
- memory by pressing Enter.
-
- It is not possible to unload resident program if one or more
- interrupt vectors originally owned by this program rehooked
- (intercepted) by another TSR. That's why the programs with
- the same intercepted vectors could be unloaded
- simultaneously or one by one starting with the last
- intercepting program.
-
- When VC exits to DOS it unloads all TSR programs installed
- after VC was started.
-
- 11. "File Attributes" command (item in Files menu) allows you to
- change the attributes, date and time of selected files. If
- you apply this command to subdirectory, attributes of all
- files in that subdirectory will be changed.
-
- 12. You can calculate the sizes of all subdirectories in the
- current panel. The size of directory is the sum of sizes of
- all files and subdirectories inside of that directory. This
- calculation can be done automatically on every file panel
- re-reading - check "Auto directory sizes" in Options menu,
- or manually - using Alt-F6 combination.
-
- 13. File search function Alt-F7 allows to search files by
- standard wildcards template or filtered by context. If
- "Containing" field is empty, the template search is going
- on, and if the "containing" field is not empty, the search
- is running according to the specified string facing the
- template. This command searches the current or specified
- directory and in all enclosed directories. Apart from the
- particular directory you can specify the drive. You may use
- *: instead of drive letter if you want looking for files on
- all fixed disks, i. e. on all hard disk partitions, all
- virtual and network disks excluding floppy drives and CD-ROM
- drives. While search is in progress you can move the pointer
- above the found files, interrupt search or switch to chosen
- file into the specified subdirectory of specified drive.
-
- 14. There is current drive label in the Info panel. You can
- create, edit or remove it, with the command Volume label in
- menu Commands or press Ctrl-F4. To remove the label you have
- simply to delete all characters in the field of the label
- name.
-
- 15. You can create enclosed User Menus. For this, you have only
- to enter full file name containing submenu instead of the
- command. If path is not specified the search will be in the
- same directory from what file executing was loaded. It is an
- obligation to specify extension .mnu as follows:
-
- F1: Formatting...
- format.mnu
- or
- C:\VC\format.mnu
-
- 16. It is possible to use macro !@ in extension files and menu,
- which creates file (VC.LST) containing list of highlighted
- files and directories, and inserts pathname of this file
- into the command instead of !@. If there is a string in
- menu:
-
- PKZIP -ex ! @!@
-
- the file VC.LST will be created and command
-
- PKZIP -ex filename @C:\VC\vc.lst
-
- would be executed. File VC.LST is created in home directory
- of VC or in directry specified in TEMP environment variable.
-
- 17. Internal viewer and editor work in both text and hexadecimal
- modes (F4 switches modes). While in hexadecimal mode Search
- operation (F7) allows to search file fragments and bytes
- sequences in hexadecimal. For example, if you specify:
-
- EB,38,A5,6
-
- VC will try to find text "EB,38,A5,6" as well as 4 bytes
- sequence: EB 38 A5 06. Mentioned string could be presented
- in any convenient way:
-
- EB, 38, A5, 6
- EB38A56
- EB38A506
- EB 38 A5 6
-
- 18. VC allows you to associate operation of Enter, F3 and F4
- keys with file extensions. Information about associated
- commands stored in so-called "extension" files: VC.EXT,
- VCVIEW.EXT and VCEDIT.EXT correspondingly. These files'
- format is following:
-
- ┌───────────────────────────────┐
- │' Comment │
- │ext: command1 │
- │ @ command2 │
- │ . . . . . │
- └───────────────────────────────┘
-
- The sign ' in the first position means that the line
- contains comments. If any other sign apart from Space, Tab
- or ', VC tries to identify extension in such a string.
- Command1, command2, ...- could be any DOS commands. If there
- is a symbol @ before the command, both prompt and command
- are not echoed to screen (as in BATCH-files). Using 4DOS or
- NDOS, the following string has to be included into VC.EXT:
-
- BTM: !
-
- This string allows to run BTM-files simply with Enter press.
-
- Meanings of all sequences of the macro substitutions using
- ! are in the lower part of screen while editing extension
- files.
-
- Viewers could be run in two ways: either in mentioned above
- way or with passing on of the parameters, including 'Socha'
- string, information about colors, mouse etc., as many
- standard viewers do. To pass on the parameters in files
- VCVIEW.EXT or VCEDIT.EXT the string has to look like:
- the command has to contain only full name of the viewer
- including extension and path; if the path is not specified,
- the viewer is being searched in the same directory, from
- what extension file was read; the command should not contain
- substitution symbols !; only one command allowed for the
- extension. For example, the following lines
-
- txt: wpview.exe
- txt: C:\VIEWERS\wpview.exe
-
- will invoke viewer in proper way, with passing on of the
- parameters, and the first line will try to load wpview.exe
- from the same directory where are the files VCVIEW.EXT or
- VCEDIT.EXT located. And if the viewer has not found there,
- internal viewer would be invked instead. But commands
-
- txt: wpview
- txt: wpview.exe !.!
- txt: wpview.exe
- cls
-
- will be executed as regular commands through the command
- line.
-
- 19. VC supports not only main (global) version of extension
- files VC.EXT, VCVIEW.EXT, VCEDIT.EXT and menu file VC.MNU,
- but also local ones. Local versions overrides main file for
- current directory. What does it mean? VC looks for "local"
- versions of this files in current directory of current
- drive. Only if local file does not exist, VC looking for
- main extension or menu file in directory, specified in
- environment variable VC=..., and if this variable not
- specified - in directory VC was started from.
-
- 20. Internal editor can edit quite long files, using all
- available free memory.
-
- 21. Internal editor can undo last character, line or word
- deletion (Ctrl-U).
-
- 22. To hide the panels and show DOS output screen, move the
- mouse into the upper left corner and click any button.
- Click mouse button one more to restore panels. This function
- is the same as Ctrl-O press.
-
- 23. Ctrl-Z displays the Tree-panel in the adjacent window.
-
- 24. Ctrl-I inserts selected filenames into command line, space
- delimited. Ctrl-[ and Ctrl-] inserts path of left and right
- panels.
-
- 25. VC fully supports logical drives created by DRIVER.SYS and
- phantom disk drive B: in systems with one floppy drive.
-
- 26. VC is fully compatible with multitasking environments like
- DesqView, Windows, OS/2 DOS boxes and does not waste
- processor time while waiting for keyboard input.
-
- 27. Country information sets the appearance of date, time and
- determines character converting from lower to upper case
- in search operation. If this function does not work
- properly, be sure the country code and code page are set
- correctly in the COUNTRY=... line of CONFIG.SYS file.
-
- 28. The program VCSETUP allowes you to set a lot of parameters
- of screen, mouse, panels, view country information and
- change color palette.
-
- 29. You can check for presence of VC in memory and get addresses
- of VC internal data structures using this INT 21h call:
-
- INT 21h:
- Set registers to:
- CX = 'VC' (5643h)
- DX = 'OM' (4F4Dh)
- AH = 2Bh
- AL - subfunction:
- AL = 0 - get pointer to left panel data structure
- AL = 1 - get pointer to right panel data structure
- AL = 2 - get address or global data varables
- Returns:
- AL = 0FFh - if VC.COM is not loaded
- AL = 0 - if VC.COM loaded
- ES:BX - pointer to requested data structure
