>Yep, that's a good point. I'm not sure what the OTHERWISE would do in this case (it's bracketting printer selection code). What should the default action be?

Hm, I just meant

CASE OS() = one thing
CASE OS() = another thing
CASE OS() = yet another thing
OTHERWISE
  *!* You've got a new OS. You could do the same thing as for the latest known version?
ENDCASE
