Production Tag

I'm having great difficulty modifying our current production. I'm rather new to this stuff and having a hard time putting the pieces together. If you could direct me to some resource other than the help file, I'd greatly appreciate it.

Here is my current issue:

At the end of the production, I want to put out an error messgage:

<Production><![CDATA[
<% //some data init %>
'Define<+ startOffset = this.Token.StartOffset; +>'
(
"procedure<@ out statement @>"
)
| (
"macro<@ out statement @>"
)
| <? true ?><% this.ReportSyntaxError("'Procedure' or 'Macro' expected."); return false; %>

...

Well, I cannot figure out how to stuff that error message into the else after the grammar is generated. By doing it the way I have above, it automatically generates an else if (true) and then an else with a false in it. That creates a compiler warning saying 'Unreachable code'...I'm trying to get rid of it.
