On Nov 18, Eduardo Bacchi Kienetz had something to say about [thelist]... >Does anybody have a routine (any language) of a CRC-16 inverted calculus ? >Or at least technical info about CRC-16 inverted ? How it is calculated... etc > >The fact is that I need to calculate de CRC-16 inverted of a string using >Clipper (programming language text-based/DOS), however it's difficult to >find something in Clipper, so I'm accepting it in whatever language ;) > >Then I can try to translate.... http://www.ibrtses.com/delphi/dcrc.html (delphi) http://www.ibrtses.com/delphi/tcrc.html (turbo assembler) http://www.faqts.com/knowledge_base/view.phtml/aid/4342 (python) http://www.efg2.com/Lab/Mathematics/CRC.htm (delpi, but mainly crc-32) http://www.6502.org/source/integers/crc.htm (assembler, commented well) http://the.wiretapped.net/security/cryptography/hashes/crc/ (C) http://www.danimalcorp.com/crc16.htm http://ourworld.compuserve.com/homepages/richard_grier/CRC32.htm (VB) That last one will probably be easiest for you to translate if you're doing some sort of DOS progamming. Just a guess, though. HTH, -- mattwarden mattwarden.com
