The= programs were written to win a competition, described on http://tnmoc.org.= uk/cipher5.htm. Unfortunately, the encoding modes for messages described th= ere have some inaccuracies e.g. the ITA2 code for " is documented as +. Thi= s means that his program either converts the + (when in Figures mode) in th= e supplied messages to " and thence to the correct ITA2 Bit Code of MSSSM (= 10001 in binary) or directly to the correct ITA2 bit Code. can any bode tel= l me what's happening on this point? Joachim has documented his programs minimally on http://www.schlaupelz.de/S= Z42/SZ42_software.html. Unfortunately, Joachim does not seem to be contacta= ble. I can be contacted on johndotaarondotroseatgmail.com in order to send = the programs by email. John
