Upps, I just got confused local rule scopes with the global scopes,
which I've been using. The grammar *is* actually correct and ANDLRworks
doesn't complain about any error when generating the file. Does
generating of your copy cause an error? Or does your changed version
cause the error? If the latter, please post the changed rule/grammar.
