 I've been trying to use Bison to create a script language for an RPG. I
downloaded a little something about YACC off the net, it has helped a bit
(I don't remember what the file was called exactly) but I still have a 
few questions.

 I want to encorporate subroutines in my language. So, I thought that I might
be able to do that like this:

 subroutine:      sub_name '(' arguments ')' '{' expressions '}'
 ;

 But I am lost as to how I would define arguments and expressions. For
arguments I need some way of passing muliple arguments, even no arguments,
with ',' characters separating each.

 Something else that is starting to bother me, would I have to do a sweep
of my entire script looking for subroutines before I could run it? Because
I'ld have to know what subroutines are defined, where they are and the 
arguments for each.

 I think this may be a bit tricky for a beginner :)
