Hi, N.B. I've had literally no personal experience with Eiffel. But ....

For DOS?? :-) BTW, I think you mean http://www.eiffel.com here. I think SmartEiffel used to (long time ago) provide a DJGPP build or at least work with DJGPP (translate to C), but I never tried it. (Very frustrating trying to get many things to work for DOS, esp. old stuff that used to work fine!) > Meyer's book discusses the motives that drove O-O languages design > > http://en.wikipedia.org/wiki/Eiffel_(programming_language) Wasn't this made into an ISO standard (2005)? Isn't it freely available (unusually)? Hmmm, apparently yes. http://www.ecma-international.org/publications/standards/Ecma-367.htm I'm not savvy nor energetic enough to delve deep into Eiffel right now, sorry! ;-) But I will say that Ada (which I also don't grok) shares a lot of features with it, esp. upcoming Ada2012 (design by contract). Unfortunately, even GNAT has poor support for DOS since the (very few) DJGPP dudes have to fix it themselves with little upstream support. Regarding Eiffel's support of OOP, it's inevitable, every language seems to have it these days. While I'm far from knowledgeable in that (overutilized) paradigm, I did learn a bit of it from Oberon and Turbo Pascal (though Delphi has yet another way of doing it). Oberon is must more minimalist in features, valuing simplicity in lieu of adding too much. If anything, it's just a slimmed Modula-2 with type extension (simple but optional OOP) replacing variant records. ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
