Soon after writing my previous message, I realized that the problem is:
BUTTON BUTTON INTEGER OF
It isn't clear which the of goes with ---
BUTTON (BUTTON INTEGER OF)
vs.
BUTTON (BUTTON INTGER) OF
Which is pretty much the classic dangling-else problem, except this is a
dangling of. Fortunately, HyperCard (the reference implementation) likes
shift.
I _think_ this means that there wasn't really a problem in the first place
(other than ambiguous grammar, of course); am I wrong?
