Come and see ...

Time and again I have a spontaneous idea that results in a tiny little program, barely documented if at all and just for the fun of writing it, sometimes useful too. I offer them here for download to anyone who is interested. All programs are free but copyrighted software without any warranty whatsoever. Most of them show a short usage information if you call them without or with wrong parameters.

• HexFind v2.1 is a very fast pattern finder designed to find hexadecimal patterns thus allowing any character in the search pattern. The new version 2.1 has a improved search algorithm, finds any combination of strings (also case-insensitive), wildcards and hexadecimal patterns optionally also in subdirectories, hidden or system files (32 bit OS/2 (28 kB) or Win32 (44 kB) with C source)
  Now there is also a Linux-only version 2.2 including source (17 kB)
  
  
• TableExtract (55 kB), a console program for OS/2, 32 bit Windows and DOS, extracting tables out of HTML files (saved locally or in the disk cache) and stores them in a plain ansi format readable by all text, spreadsheet and database programs (32 bit OS/2, 32 bit Windows and DOS, with common C source)
  Now there is also a Linux version of TableExtract, including (same) source & Makefile (14 kB)
  
  
• HowLong (18 kB), a console program for OS/2 and 32 bit Windows, measuring execution times of other programs using the built-in high resolution timer (32 bit OS/2 and 32 bit Windows, with common C source)
  
  
• The CRC Program (52 kB), based on a program by Gary Brown, calculates cyclic redundancy check checksums on files with the CRC-16 and CRC-32 as well as the CCITT polynomials (16 bit DOS, 32 bit OS/2 and Win32 with C source)
  
  
• Euro-Umrechner (74 kB), also a small OS/2 PM program to convert amounts among the currencies of all Euro countries (32 bit OS/2 - Warp+, German only)
  
  
• Significance Calculator (87 kB), a small OS/2 PM program using the statistic functions above to calculate significance levels (32 bit OS/2 - Warp+)
  
  
• Statistic and random functions (3 kB) are ANSI C libraries with powerful random functions (replacing the library functions rand and srand) and functions calculating the quantils of the Z, Student's t, Chi square and F distributions
  
  
• HRTimer 1.1 (24 kB), the well known high resolution timer for OS/2 (resolution: 1 microsecond) in a new, enhanced version (OS/2 driver with source and sample code; unfortunately not really useful, as OS/2 v2.0 and up provides the same functionality with its builtin DosTmrQuery-functions)
  
  
• Pi and Euler (19 kB) are some programs to calculate π or e up to more than 150000 decimal places (16 bit DOS with C/Asm source)
  
  
• The Primzahl (prime number) Project (55 kB) finds primes and factors numbers up to 2⁶³ (1E19) (16 bit DOS with C source, German only)
