thanks guys!!! that clears that up.
do you know about the order the files are executed though? I need to know, because if I use interrupts in one file to control the speed of a motor, it needs to be read before the user_routines_fast.c file so that the variable's values (the extern one I was asking for help earlier) can be sent to that file.
do you see what I mean?
also, can I use the
volatile unsigned int my_int;
then assign its value to a static variable inside a method in another file?

(back to the question obout the file execution order) it would be really cool to be able to tell the controller to rescan the file (or whatever part of the .hex file it is) of course, it's better just to know which ones are done first and which are done last.
by the way, I feel dumb for asking this, but what's the difference between frc_rc and edu_rc.
