Hi,


Is there any way i can configure yacc or some other tool to tell me,
at each step in a parse, the set of tokens that may follow the current
token? I am currently doing this by hand, and it is, as they say,
a tedious and error-prone process.


Any pointers (into shared memory, of course) will be appreciated.


Thanks,


Jerry Ratner
