[antlr-interest] Problems - KCSParse

[DG l]

Hello, I've recently only begun delving into the world of parsing as part of 
a project. I'm attempting to use antlr on the example KCSParse provided with 
the download. Several false starts later I'm getting errors along the lines 
of

>From what I can gather this warning is telling me that it's something to do 
with the lookahead. I have not modified the base examples in anyway. So my 
question is thus; where have I let it all go wrong? Your advice is 
appreciated.

Software Engineering is guesswork, constrained by business. Once we can 
reduce money to binary format it will flow like data and programming shall 
be pure. --unknown
