[antlr-interest] Using ANTLR 3.1 to parse macros (for a Macro Assembler)

Hello Everyone,
I'm working on a macro assembler for an embedded platform (trying to
improve on the existing DOS-based assembler). I'm new to ANTLR3 and I've
been trying to figure out how to handle the assembler macros. They work
like C pre-processor handles #define's -- it's just text substitution. I
believe I understand how the old C pre-processor example works:
http://www.antlr.org/share/1090897436819/cpp.g
but that was designed for the older version of ANTLR and I haven't figured
out how translate that example into ANTLR3. In ANTLR3, how do I get the
parser to switch to a new lexer in the middle of the processing and then
retry the match? Or is there a different/better way of handling this in
ANTLR3? I'm using the CSharp target. So far I haven't had any luck with
the book, the online manuals, or google.
Thanks,
