You may have a point: A language that has the capability to make a a well-defined interface, ie a language encouraging components, may well mean that the type of applications it's used for are, by their very nature, 'portable-friendly'. OTOH Embedded systems, avionics, air etc don't strike me as being more inherently 'similar' to one another as, for example, spreadsheets or operating systems. Any evidence on this one? > I just do not see > how once I start throwing windows up on the screen and responding > to messages, that that code is porting anywhere. OK, so GUIs vary. My point is that even in two implementations where the GUI is isolated/wrapped and so not "part of the problem", that portability with C++ (forex) is considerably less than great. > Last time I was in Barnes > & Noble I saw "Ada 95 for C and C++ Programmers" by Simon Johnston, > from Add-Wes.
