[Oberon] How2 calculate First and Follow and check if LL(1)

[Srinivas Nayak]

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
