The major difference between J6 and later versions is the IDE. The core language changes between J6 and J7 are very minor, and for most Jers' purposes, ignorable; there are no language changes in J8.
The purpose of introducing J7 was to give the J programmer access to more modem GUI-building tools. J8 improves upon this modernization and will eventually replace J7. All this is long way of telling you that if you don't need to build windowed apps (for personal use or distribution), and getting J7/8 to work is a hassle, you don't need to upgrade. If J6 works and you like it, use it.* -Dan * I mostly use J6 because it's familiar and reliable, and easier to install on new machines. I do have both J7 and 8 installed and working, and while I like the editor window in those IDEs better, the J6 IDE feels snappier and more responsive to me, particularly on startup when I want to do a quick desktop calculation (and since I only use J for desktop calculations and headless scripting, the wd GUI improvements are irrelevant to me).
