hi,




I hope you can help me. I try to explain my problem.


I also working on a interpreter which use the EBNF grammar. But there are
some points I don't understand. Please take a look at this page:






http://infos.osk.uni-bielefeld.de/fakoinf/htmldata/projekte/pcomp/gesamt.htm






It's only a German page, so please look at the G = (T, N, S, R) description.


Is the R assignment correct over all ? Why is the Buchstabe (character) and
Ziffer (numeral) quoted ? They aren't terminal symbols. And also where they
are fixed ?


Is a character and numeral a special Keyword which standing for "A".."Z" &&
"a".."z" and "0".."1".


thx and best regards from


Christian
