DDS Download Summary

If you get sent to the TOP of this listing, it probably means that I have not done a description for that download yet!
Please let me know so I can fix!

ACC
Adapt C and Compile

A tool to automatically "adapt" C source code from one compiler toolset to
another and Compile it. Includes LCC.ACC, definitions to go from my Micro-C/DOS
to LccWin32 - a Windows32/64 development environment.
BASIC
A simple BASIC interpreter. Makes a good example of how a "scripting"
language could work in DVM.

Lots of information in the opening source code comments.
BFS
Binary File Search

A tool to easily search a binary file for occurances of one or more
sequences of bytes.

 Can search very large files, for many search sequences.  This can be slow...
 Suggest using the .DVM instead of the .COM in slower emulators (like DosBox)

 includes a tool to "trim" output, so you can search for more unique sequences
 than the part you need without keeping the surplus part.

 use: (no arguments)
 for more information.
CGS
C Global Symbols
 Easily track references to Global Symbols within C source files.
CHT
C Help Text
 Processes a C source file and converts special comments into a help
 data file which is optimized to reduce spaces.

 For more information, use: CHT -?
        and to easily edit: CHE -?
 
 See CHTHELP.C for an example.

Much of my source code will require this utility to generate a needed Help.H
CKW
ChecH Web page source
 A little tool I wrote to help build and maintain manually generated .html
 web pages.
CLIPTOOL
Some utilities to ease moving text strings around via the Windows clipboard.
    TXT2CLIP: Select predefined string(s) and put in clipboard.~BR;
    CLIP2TXT: Paste directly into a text file.~BR;
    CLIPLIST: Fill in a named list with paste operations.~BR;
COMP
A more powerful COMPare command. Can:
    Compare whole directory trees
    Show what has changed
    Show what hasn't changed

 use: COMP  (with no arguments)
 for a command syntax summary.
CSANA
 Some "Quickie" tools I wrote to analyse C sources and more easily clean up
 after it had suffered from hours/days of debugging.
CSLIST
 Produces a C format list of strings along with #defines for their
 position in the list.  Run CSLIST for more detail.
CSUCLC
 In Jan 2021, I connected to usenet after years of inattention.
 Not having a recent newsreader or feed, I used "Google Groups" to check it
 out, and comp.lang.c was one of the first places I went, and got into a
 few "discussions" which resulted in me writing some somewhat useful tools
 to manipulate C source:

    REMove COMments from C source code (response to a posted challenge)
    Conditional Line Comments (make options without using up non-comment lines)
    ReFormat Csource from GoogleGroups
    C source MUNGEr
DBBD
DosBox FloppyDisk builder
 Creates minimal/independant DosBox setup that boots pure DOS
 useful to handle things that simply "Don't work in DosBox"

DBD
DdsBuilD
 A tool to simplify building with Micro-C

DBUTIL
Various utilities I've written to enhance the experience of using DosBox.
 These are mainly commands that are either missing or have a reduced
 capability in DosBox as shipped:
    BAX     More powerful Batch processor
    COMP    Missing in DosBox
    CP      Improved Copy
    DBSC    DosBox Screen Capture (useful as DosBox can't redirect stderr)
    EDT     My text EDiTor
    FIND    Missing in DosBox
    GDBCM   Gets DosBox config / mount information into ENV
    KEYSUB  Make DosBox workable on non-PC keyboard

    CHANGED*    Set of tools to backup/manipulate recently changed files
        So far this has been the best of my automatic backup tools!
    Also: EDT, FCT, FCB, FVT and FCB
        Tools used by some of these

DDLINK
Transfers files via COM, LPT or NETwork
 Single .COM needs only a "packet driver" for network.
 Nice "split screen" (show/select both sides) user interface
 Has options for non-interactive (eg: in .BAT) transfers
 Can "bootstrap" itself to a new system (over serial).
 Includes: DDLCMD.C, see how to implement link protocol!

 Best way I've found to move things between older & to/from new systems!

 See "PKTDRV" for LOTs of network card drivers!
DDVM
 Decrypts file(s) to an internal DVM RAMdrive, then runs a .DVM program which
 can access the decrypted data, all the while NOT keeping the decrypted data
 anywhere on your system which is easily readable/accessible.

 This helps make it difficult for malicious software to read your data files.
DDSDNLD
Validate DDS download files
 Confirm a downloaded file is exactly what I published!
 Requires DDSDNLDB.ZIP from my site, see 00README.TXT contained therein.

    Put both the DDSDNLD program and DDSDNLD.DAT in the same directory as
    the downloaded file(s), then run DDSDNLD.
DDS
Use this to decrypt .DDS files I send via email (usually encrypted .ZIP)
 I encrypt them because many ISPs won't allow sending or receiving certain
 types of files (like executable) and they do check inside .ZIP attachments
 for these "dangerous" file.

 Unfortunately I am usually sending tools/updates which contain file types
 that are disallowed.

 For more information, use: DDS -?
DECZIP
Tool needed to decode encrypted .ZIP files that I may send to you.
Often my .ZIPs contain executables and other file types that various ISPs
block from email attachments (even within .ZIPs).  MY work-around is to
encrypt the .ZIP into an unrecoganizable binary "blob" which you need DECZIP
to convert back to it's original form!
DLCMD
DirectoryList CoMmanD
 Easily perform common commands on a "Directory Listing" formatted text file
 containing the file names.
  This can be the output of: DIR, XDIR, FFF, FFSAME etc.

 Use:   DLCMD (no options)
        for more information.  
DVM
Dunfield Virtual Machine
 This is a virtual processor and complete system that lets you easily
 create and run simple but powerful programs "pretty much anywhere".
  I have recompiled most of my (originally DOS) tools and utilities (available
  on this site) to make them also usable with DVM/Win32/Win64/Linux!

 This free demo works on Win32/64 (also available for Linux)! ..BUT..
  DVM can be ported to pretty much any system where you want to run general
  purpose small/powerful applications with little overhear and complete
  control over what they can access/do.

 My own Micro-C (a fairly well regarded C compiler from the 80's) makes it
 simple to create DVM programs in C - with development complexity similar to
 other tools from that era... much less complex that "modern" offerings!

 Contact me if this is of interest.
DVML
Dunfield Virtual Machine (for Linux)
 A  preliminary port of DVM to Linux
 see the DVM package for more information on DVM.

 for a command syntax summary.
FFF
FastFile Find
 A set of tools to make it easy to find and get information about files which
 may be spread over multiple large directories and drives.  Supports powerful
 MATCHing capabilities and uses an efficient database to make locating files
 very fast, no matter where they are spread over.
    FFBD    Build the database from directory trees
    FFB7Z   "" from 7ZIP listings (supports common archive formats)
    FFF     FastFile Finder
    FFCMP   Compare files using two databases (see whats changed)

 Includes DOS/Win32 as well as DVM/Win64 versions.

 See FFF.TXT for more information.
FINDSYM
FIND SYMbols in source files
 Makes it easy to see where symbols are being used in various files.
 I use it mainly for C source code, to see where (and if) symbols are being
 referenced.

 Unlike traditional viewers, FINDSYM knows what constitutes a symbol, lets you
 easily select them within the source file, and can search forward and backward
 for them, all the while highlighting all occurances showing on the screen.

 2022/08/02 added FSCS, less powerful but simpler/easier
FTOOLS
File TOOLS
 These tools help collect/orgnize and maintain frequently changed "working"
 files.  Includes:
    FAW     Archive Working files
    FCL     Commands from List  \
    FCB     Compare Binary       >  help find and maintain files
    FCT     Compare Text         >  with the same name or content

KEYMAP
Remap keys using Windows registry entries.
 This uses scancodes, so complete physical keys are remapped.
KEYSUB
Installs a tiny TSR (DOS) which remaps keycodes returned by: INT 16h AH=0
 This lets you remap key functions independantly (ie: Shift, Alt and Ctrl).

 I use it to make DosBox on tablets workable with non-PC bluetooth keyboards.

MC
Micro-C compiler
 This is a pretty capable C compiler that I developed back in the 80's with
 the primary focus of being suitale for very small 8 and 16 bit embedded
 systems. It has received many favorable reviews and won various awards over
 the years.

 It is known to generate very efficient code, and is the primary tool I used
 to develop almost all of the tools and utilities available here.

 Micro-C is a product available for about a dozen different small processors,
 with free versios available here for: DOS/Win32 and DVM/Win32/Win64.
MKPKG
