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?
