[SNIP]

 does anyone know of a program that changes BE6C and BE6D?

Not sure what you mean Mike.
Those are pointers in the global page that point  to a pathname buffer.

BE6C/6D VPATH1   ;Pathname 1 buffer
BE6E/6F  VPATH2   ;Pathname 2 buffer  (RENAME)

Basic system itself will change those pointers as it goes about its
business.
