I hope someone will be able to provide a quick answer to my question.
A simple yes or no will do.
I have seen a full grammar for GREP in LALR1 form but never in LL1
form. I have tried to develop such a grammar in strict LL1 form using
LLGEN to check my results and no luck. It seems that any occurence of
an embedded Kleene closure (ie, ".*") fouls up the system.
Am I right in assuming that the required grammar can not be expressed
in LL1 form or have I a whole lot more to learn?
