Can an M4-program read data out of an C-program?

[Amaury Ampe]

Hi,
I have a question about M4 of which I hope you can help me with.
I'm a master student working on a robot for my teaching practice. The  
robots program is written in 3 languages (M4, C and ASSEMBLER for the  
PowerPC555). The main code is M4 and depending on which of the 2  
processors the code is for, it's mixed with one of the other 2.
My job is to write a program that would make it possible to change the  
values of the robots controller without having to know anything about  
programming.
I'm planning on writting a program in C where the user can fill in his  
values. Those values should then be loaded into the M4 main program.  
Can you tell me if this is possible? I should mention that the values  
are actually ment for the PPC555 so I will have to refer to them in  
ASSEMBLER.
I'm quite new to programming in general and completely new to M4, so  
any help would be most welcome.

Kind regards,
Amaury
