Programs and Source Code

These are various little programs, utilities, and libraries that I have written over the years. Distribution and use is free and unlimited unless otherwise noted.

Microsoft
MS-DOS and Windows

Caveat:
Unless otherwise noted, some of these programs were originally written and compiled on 16-bit MS-DOS, and may not work very well when run on 32-bit Windows, especially in the way that they fail to handle long file names.

• bin2bmp.exe
  Converts a binary data file into a BMP image file.
  Some people, to my surprise, have actually found this program useful.
  [source code]
• bmpdump.exe
  Dumps the contents of a BMP bitmap image file in hexadecimal form.
  [source code]
• cat.exe
  Catenates the contents of one or more files, writing to the standard output (a la the Unix 'cat' utility).
  Similar to the DOS 'type' command, but better. Has several options for converting between different end-of-line conventions.
  [source code]
• chtime.exe (32-bit)
  Modifies the timestamp of one or more files (a la the Unix 'touch' utility).
  [source code]
• crlf.exe (32-bit)
  Converts newlines in text files.
  Handles CR, LF, CR/LF, and NEL newline sequences. Handles 8-bit ASCII and ISO 8859-n text files, 7-bit ASCII with parity, and UTF-8, UTF-16, and UTF-32 Unicode files.
  [source code]
• detab.exe
  Converts the tabs in a text file into spaces.
• diskuse.exe
  Displays the free and used space on a disk drive.
• ebcdic.exe
  Converts an ASCII file into EBCDIC or visa versa.
• entab.exe
  Tabifies a text file by converting spaces into tabs.
• filldisk.bat (16-bit and 32-bit)
  Fills a hard drive with many large random data files, effectively erasing all the unused and deleted file blocks on the drive.
  [documentation]
• fsplit.exe (32-bit)
  Splits a large file into several smaller files.
  The smaller files may br recombined using the DOS 'copy' command or my 'cat' utility.
  [source code]
• fstat.exe
  Displays information about files.
  The information displayed can be tailored using a number of formatting options.
• gifdump.exe
  Dumps the contents of a GIF bitmap image file in hexadecimal form.
• hdump.exe (32-bit)
  Dumps the contents of one or more files in hexadecimal and character form.
  [source code]
• head.exe
  Displays the first few lines of a text file (a la the Unix 'head' utility).
• reboot.com
  Reboots the computer.
  Admittedly, this is not very useful.
• RightFax utility programs (32-bit)
  

  rfaxdelegate.exe	List and assign RightFax user delegates.
  rfaxlist.exe	List faxes on a RightFax server.
  rfaxmark.exe	Mark faxes on a RightFax server.
  rfaxping.exe	Check the network connection to a RightFax server.
  rfaxusers.exe	List users on a RightFax server.
  readme.txt	Documentation file.

  These programs require the PATH environment variable to include the directory containing the rfwin32.dll library that was installed with the RightFax client software.
  [source code]

• scram.exe
  Encodes or decodes a binary or text file into a text-only format suitable for emailing. Handles different end-of-line conventions for text files.
  [documentation]
• snow.exe
  Fills a 320x200 VGA display with 'snow'.
  Admittedly, this is not very useful.
• tcopy.exe
  Copies files to a destination directory if they don't exist or are out of date. Similar to the DOS 'replace' command, but better. Has several options for controlling how the copying takes place.
• tee.exe (32-bit)
  Copies standard input to standard output and to one or more files (a la the Unix 'tee' utility).
  [source code]
• tod.com
  Simple utility that displays the time and date.
• unicode.exe
  Converts an ASCII text file into Unicode or visa versa.
  Handles big-endian or little-endian encoding.
• uniq.exe (16-bit)
  Removes adjacent duplicate text lines from standard input (a la the Unix 'uniq' utility).
• uniqln.exe (32-bit)
  Removes adjacent duplicate text lines from standard input (a la the Unix 'uniq' utility).
  Handles CR, LF, and CR/LF newline sequences. Handles 8-bit ASCII and ISO 8859-n text files, and UTF-8, UTF-16, and UTF-32 Unicode files.
  [source code]
• vdate.exe
  Displays the current date and time.
  The output can be tailored using a number of formatting options.
  [source code]
• vecho.com
  Simple utility for writing arbitrary characters and escape sequences to standard output (a la the Unix 'echo' utility). Similar to the DOS 'echo' command, but more sophisticated.
  [source code]
• vfind.exe (32-bit)
  Locates file and directory names matching specified wildcarded names and other search criteria. Recognizes long file names if running in a Windows shell.
  [source code]
• what.exe (32-bit)
  Searches for "what" strings embedded within files (similar to the Unix 'what' utility).
  Such strings are prefixed by the character sequence "@(#)" and typically contain source revision information about the file. Many source code revision control systems, notably SCCS, use these embedded "what" strings to track the source code used to build executables and libraries.
  [source code]
• whence.exe
  Locates the files corresponding to specified commands by searching the current PATH settings.
• wordc.exe
  Simple utility that counts the number of characters, lines, and words in one or more text files.

Source Code

• Source directory containing source code for various utility programs and libraries.

Java

• Source directory containing Java source code for various utility programs and libraries.
• YACC/M
  A parser generator based on YACC that generates parsers in Java for LALR(1), LR(1), and MLR(1) grammars.
