I'd prefer not to encourage SetFunction whenever possible, because you
never know what will happen when things get combined, or when Commodore
revises the OS, or whatever. When there is any possible way to do
something not using SetFunction, I'd do it … the humor in this being that
both FastFonts and BlitzDisk use SetFunction, because there is no other
way. Both are "safe" if other programs sit on the same vectors, and for
both I spent much more time considering boundary conditions than I did
writing the actual code. For shared screens, I don't think there is any
safe way to guarantee existing programs with CUSTOMSCREENS will all work if
you open a window in their screen, even if you do SetFunction the screen
stuff … that's why I haven't done anything with TxEd on shared screens
yet, because I can't support it- …cheath
