Yes?              No, the difference between SLR and LR(1) is that FOLLOW sets are a way       too conservative estimate (i.e. a superset) of the possible symbols,       which may appear after a production, thus resulting in reduce-reduce       conflicts.              ~velco              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
