Software Algorithms - ANS Forth for
32 bit PC Forths, mathematical, CRCs, Hashes, also

useful!
Now
with AES , SHA-256 , Average and an updated WSA
interface :
\
Average.f 2014 Nov 07 Running averaging of n data readings. Howerd Oakford www.inventio.co.uk
\
Uses a buffer size that is a power of 2 for efficiency
\
Calculates a running total by adding the current reading and subtracting the
\
n'th reading, so looping
over many values is not required - see UpdatePulses
\
You can extract averages over a different period of
time from the same average buffer.
\
For SwiftForth - www.forth.com - a 32 bit ANS Forth for the PC
\
include Average.f ttAv \ will show a demo using the MiniScope ASCII display

USBclarify.zip V1.0 2014 May 14 - SwiftForth source and zipped executable to
display information about USB devices as they are plugged into your Windows
computer
Unzip all the files from USBclarify.zip into a folder, irun SwiftForth and in the SwiftForth console use cd c:\yourfolderpath and type include USBclarify.f , or click on | File | Include | and select the file USBclarify.f , then type USBclarify <cr>
Displays
the COM port assigned to a USB serial device when it is plugged in.
Still not the best code in
the world, but mature and useful enough to leave home…
USBclarifyFull.f this file includes MD5.f and usb.ids in-line – open it in your browser, ctrlA ctrlC then paste it into a SwiftForth console with ctrlV, wait half a minute then type USBclarify <cr>
Just for fun, to see how it can be done - its one big file, so please be patient :-)
USBclarify.f V1.0 2014 May 14 Howerd Oakford www.inventio.co.uk
Displays when a USB device is connected and disconnected, including which COM port a USB serial device is assigned to
Demonstrates how to use Windows device notifications
Defines HID and other constants and structures, including support for GUIDs
Compile using SwiftForth, available from www.forth.com
The file usb.ids from https://www.linux-usb.org/usb.ids must be in the local folder in order to compile this program.
Thank you to the Linux guys for making this information available :-)
Cweed
Now
with support for C++, Lint and with Folder Scan, and works under Windows7 Also NumName human readable hash values…
Cweed is a C source file weeder written in Win32Forth.
It only changes whitespace (formatting) and does not otherwise change the content of the file.
This is analogous to weeding a garden, where the plants are left untouched but the bits between may be seriously modified.
Cweed is an experiment in specifying a coding standard in the form of an executable program.
Code prettifier for C and header files. Converts tabs to spaces, re-formats, checks for Lint errors.
Creates a folder report listing files and their formatting health status.
Shows the CRC32 and MD5 hashes for each file.
Lots more features too...
USBloader
2013 Apr 08
The USBloader
system is designed to make it easy to make any USB disk drive bootable.
This allows
you to run your choice of operating system on your computer, from a USB drive.
Program
execution is in Real Mode on an 80x86 PC, 80386 32 bit or higher is required.
USBloader supersedes USBboot which is no longer supported.
Download : USBloader2013Apr08release.exe self extracting zip file or USBloader2013Apr08release.zip zip file.
Disclaimer : using USBloader.exe to make a USB drive bootable should not affect the other files on the drive.
Use it at your own risk, and backup up
everything on your drive, or use a brand new one, just in case…
Now with new Floppy Disk Formatting features : press ctrlF4 to convert the cfUSB.img
file into a floppy disk image and copy it to the inserted drive. This can be
either a USB floppy disk drive or USB drive, in either case the disk will be
re-formatted and all data will be lost.
There are two warnings before this happens…
More info : USBloader 2013 Apr 08
Includes a FAT32 file system boot loader written in NASM assembler
Corrected two typos in the HDLC CRC16 calculation in Forth and added two new CRC16 calculations :
crc16hdlc.f crc16.zip ( the zip file now contains all three CRC16 files )
\ *****************************************************************************
\ crc16hdlc.f 2012 Apr 11
\ CRC-16 for HDLC calculation using a table
\ 16 bit FCS lookup table per RFC1331
\ Thanks to :
\ https://www.mavi1.org/web_security/cryptography/hashes/crc/crc-16-hdlc.c
\ Note that this code defines "#define FCSGOOD 0xF0B8"
\ whereas I define "$0F47 constant CRC_VALID" which is bitwise inverted.
\ This is because CRC16 returns the actual value to be sent in an HDLC packet
\ Also note that at least one online CRC calculator does not include this CRC.

crc16modbus.f as above for ModBus
crc16-a.f as above for ISO10373 and ISO14443 type A (and B )
Announcing Win32Forth6v05H.exe ( and Win32Forth6v05H.zip zip version ) , the Win32Forth system used to create win32for.exe, as supplied in the Cweed packages.
The ‘H’ is for Howerd, although I have kept as much of the original V6.05 as possible.
This version of Win32Forth runs under Windows7 ( Ultimate 64 bit ) and does not offend my anti-virus program.
I have kept the original help file by Tom Zimmer et al. but moved it to load from the local directory without having to have the source tree present.
This means that it works with the Cweed package. I merged changes in the OS detection words from V6.14 so that it recognises Windows 7…
I have also added some aliases such as
loc for locate , to locate a word’s source,
\\ for \S to end compilation of a file
and some new words :
g to invoke the editor, and
tt that, if you are in directory Cweed, will load file Cweed.f
There is a readme.txt file to get you
started, and the exe package ( over 13 Mbytes ) unzips
and runs with minimum fuss.
New Forth book online :
Chuck Moore, the inventor of the Forth programming language has published his
book from 1970 online.
It gives a fascinating insight into the
rationale behind Forth : PROGRAMMING A

View the readme file here
Full assembler source files, NASM assembler, colorForth source and DOS batch file to create the colorForth image, plus floppy.com to download it to a floppy disc :

Real colorForth running really slowly...
A tradeoff between working on (just about) any Windows PC against execution speed.
Double left click ( run ) go.bat to start the cf2010.blk version of colorForth
in a bochs PC emulator.
bochs is available from https://bochs.sourceforge.net/
bochs is truly wonderful! Thank you to all the bochs developers...

PPP.com is a DOS based program to analyse, display and create PPP and Internet protocols. PPP.com is the current evolution of a general purpose scripting environment, adapted to the Point to Point Protocol. Currently it can open a PPP connection to an ISP and send DNS, ICMP, UDP or TCP packets to any IP address on the Internet. PPP.com has not been optimised for program size, as it is a 16 bit Forth program, and nearly fills up the maximum 63K bytes allowed for a .com program. This includes 4K of help text, roughly 3K of protocol descriptor text, an editor, 8086 assembler and Forth compiler. It supports five tasks, two of which monitor PPP and IP packets on each of COM1 and COM2 serial ports. It is programmed in a 16 bit DOS 8086 Forth to allow easy porting to 8 or 16 bit embedded processors.
Cweed is a C source file weeded and scanner. It only changes whitespace (formatting) and does not otherwise change the content of the file. This is analogous to weeding a garden, where the plants are left untouched but the bits between may be seriously modified. Cweed is an experiment in specifying a coding standard in the form of an executable program. Cweed is also useful for scanning a file for control characters, removing tabs, or just viewing what is actually there, not processed and formatted by an editor.
cfdos is a DOS program to display colorForth pre-parsed source blocks. This program will work on any computer that runs or emulates DOS, and allows you to view colorForth source, in both normal and "colour blind" mode. It features a file listing utility (F6) which displays all files of type *.BLK in the same directory, and can copy them to a formatted floppy disk. colorForth Explorer Edition is the latest colorForth stand-alone operating system, packaged together with a Windows/DOS program to display colorForth source and create bootable floppy disks.
Don't be deceived by the fact that colorForth boots from a floppy - this is an experimental state-of-the-art operating system for a PC.
See The colorForth Magenta Variable and colorForth and the Art of the Impossible my first impressions of colorForth
