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

[John R. Strohm]

Calculation of First and Follow is covered in the Green Dragon Book.  I'd 
expect it to be covered in the later books as well.

And, as always, Google is your FRIEND.  "first follow sets"

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
