Dear All, Lets say I want to modify Oberon language. I would then like to check if my modified language is LL(1). Towards that end, I would also like to calculate First and Follow set of symbols for each of my non-terminals. I see a nice program EBNF.Mod How can I modify this program to 1. calculate First and Follow set of symbols for each of my non-terminals. 2. check if my language is LL(1) With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/
