Okay. I would like to thank you all for allowing me to figure out the errors of my efforts. No sarcasm.
I found out that since Bart was nice enough to get me started, even though it was a Java example, I didn't realize where my Python program was starting and what was antlr code. I discovered that my line: insideFunction = False; was causing the java compilation to complain so I moved that inside my def. I also realized that the code: $f.text.toString()); is java and is not part of antlr. Since I was using language=Python, it had no idea what I was trying to do. Now when I run my program, all I get is: STATEMENT -> (JavaScriptParser.statement_return object at 0x02168C90) What I want to see is the line of javascript code from the .js file I'm reading from prefaced with either STATEMENT or FUNCTION. Can anyone help me with that? I've watched the tutorials and read through the book, but I cannot for the life of me figure out how to get the line of javascript to print. Please help... Thomas J.
