Actually, Bob, the standard was pretty clear on these cases, telling
us that a NOT immediately preceding a relational operator is a part
of that relational operator and is otherwise a logical op.  Hence,
your examples would be expanded thusly:

     IF a = b AND NOT g   =>   IF a = b AND NOT a = g

     IF a NOT = b AND g   =>   IF a NOT = b AND a NOT = g

I'm still working on the rest of your message :)
