If you are simply trying to force GRASS to use a map in a different mapset,
specify the mapset when choosing the map: <mapname>@<mapset> , elevation at PERMA-
NENT, etc. As long as the named mapset is in your search path, GRASS will use
the specific map that you name. 

As far as changing mapsets on the fly goes, your .grassrc file seems to control
this function as far as most GRASS programs are concerned. If you change the 
mapset in your .grassrc file, it believes that you are now in another mapset.
Obviously, you must have permissions for this mapset. *I do not recommend this
approach!!*
