Hello,
    I need to create a parser which proceeds the text file and reads one
statement. I want the JavaCUP to do this, but if the grammar contains
only rule for one statement (not a list of statement), the parser
throws an arror if the input file contains more than one statement. I
want the parser to let the rest if input file unchanged. JavaCUP
expects the end of file instead of the first token of a next
statement. Does anybody know how to tell to the parser do this ?


For sure I do not know if is that possible.
