You can't do it that way - or at least it won't be easy.
Easiest way is to make external "variables" -c file, where
you declare _all_ variables, and include it to every other file.

Practically it would be something like this;
vars.c:
  #include <vars.h>
  <define variables here, example; char room [30];>
vars.h:
  <define external variables; extern char room [30];>
room62.c: (one of your part files)
  #include <vars.h>
  <other includes and everything...>
main.c: (main routine)
  #include <vars.h> ...
