Hi Ian, When I was reading the updated article when I came across some strange characters (first line below the C++ version of BlackScholes)
"This program includes as its first argument the letter 'Äòc'Äô for a call option, and 'Äòp'Äô for a put option, and then discriminates between the two by an if/elseif control structure." I tried this on IE7, Google Chrome 2.0.172.33 and FireFox 3.0.7 and it appears the same in all three browsers.
