However, my point is that I have only just started the development of my grammar and I don't want want to spend time on error handling yet. It is also the first time I am using ANTLR (I have used Flex/Bison before) and I was just looking for a simple way to detect whether or not any parsing errors have occurred. The current behavior is quite confusing for a first time user, so I'd say the default display error method should increment the error count. Even the error count method doesn't seem to be well documented, I only found it by looking at the source code. Thank's anyway, my problem is solved.
