   "ambiguous condition:   
   A circumstance for which this Standard does not prescribe a specific behavior   
   for Forth systems and programs."   
      
   "undefined" and "not prescribe a specific behavior" seem much alike to me.   
   Either way, the Standard is saying don't do this thing.  It's not as if   
   they'd said nothing about it and left it up to you.
