[antlr-interest] Problems with first example

[Bill Ramsay]

Hello,

I'm new to Antlr and am trying to work through the Definitive Guide.   I can't seem to get the first example to work.
I create the .g file and lexer and parser classes fine.   I compile my example test program fine.   And it runs fine.  Except for one minor problem - it doesn't work.   I put a few debug lines in the code and  it gets hung up on the line:

    ANTLRInputStream input = new ANTLRInputStream(System.in);

It never seems to move past this line.   The code used is copied from the book,page 10 - 12.    

Bill
