OK, but is Q’s lexicon an exclusively 1-1 correlation?
I am dimly recalling that we had no such guarantee, at least in the past.
There is a q lexicon online but I am a bit fearful to post it lest i trip over some fr rule. It does not appear to contain “MOS.” I recall a FR lexicon in the past but I can no longer find it in a quick search (i do believe i can recall who maintained it in the past but that may not help, at least on short notice).
Have you bothered to read the links which are in the first dozen or so posts at the top of every new Q thread?
