C++
As I recall, C++ cost about $200 for registered users of the Lattice 5.0
compiler, though you might want to check with Mike Roth (76566,1137) to
make certain. As for your configuration, I would think you would be
alright. C++ comes with its own include files, and a couple of new
commands, but if you can run 5.0, there should be no problem. One last
thing: be prepared for one heck of a learning curve! There are so many
new ideas to OOP that it takes a while to get them all straight (though I
figure I'll have them all down in a year or two :). Good luck, enjoy, and
let me know if I can answer any more questions for you.
