The master object will probably append a .o to the name.
Variables that has the type modifer 'static' will not be saved. Example: static int xxx;
If inheritance is used, then it might be possible that a variable will exist with the same name in more than one place. When restoring, only one of these variables will be restored if encountered in the save file. A good practice is to have verbose and unique name on non-static variables, which also will make it more easy to read or patch the save file manually.
