Hi,

I am writing a small parser in ocaml, using ocamlyacc. I need to define 2
start symbols in my file parser.mly, but I don't know how to use them. The
name of the 2 start symbols are "main"and "main2". I know how to use one
start symbol, as here(taken form "calc.ml"):

 let _ =
          try
            let in_channel = open_in "lines.txt" in

            let lexbuf = Lexing.from_channel in_channel in
            while true do
              let result = HorsParser.main HorsLexer.token lexbuf in
                Hors.print_pair_list result;
            done
          with HorsLexer.Eof ->
            exit 0

but I don't know how to call the function "HorsParser.main2".
I want to parse a part of the file "lines.txt" using the rule "main", and
then, the other part of the file using "main2". Is this possible?
 I tried to call "HorsParser.main2", but I got a "Parsing.parse_error".

Thanks,
Ligia
