Hi,

I'm writing a game, OPES (see sig), which will use some sort of run-time
script. Currently, I'm planning to use the Seer library to implement
this, but it looks a bit over-complicated for what I would like to use
it for.

In the FAQ, we are told that the DXE mechanism is extremely simple
(which is what I'm looking for), that you can't unload modules (not a
problem) and that you can't access variables in the main executable
(there aren't any global variables; it's C++ with classes). The only
thing that may be problematic is that you can't access functions in the
main program.

So, a few questions:

 1 - can I create a large module, using several different input files? 
     It is likely that there will be a lot of code in the module.

 2 - if I pass a pointer to a function in my C++ code, can the DXE call 
     that function?

 3 - will I be able to call the DXE from C++ code (as opposed to C 
     code)? Connected with this, will I be able to write the DXE in C++?

Thanks for your help + time, and bye for now,
