Hi,
I've gone over the docs but I don't get how to fix lexical
nondeterminism between keywords and identifiers. My (relevant) lexer
rules are printed below. I keep getting nondetemrinism between ID and
RESULT on the characters 'r' 'e' - oh, k is set to 2. I've mucked
around with the test literals feature and that doesn't seem to help.
Someone please put a dumb newbie out of his misery :o)
thanks,
Peter.
