I think you're referring to environment variables. Those can be
accessed from within Python using os.getenv() or os.environ[]. 
However, the OS may impose limitations on the total space used by
environment variables, so you shouldn't use too many of these.

Also, environment variables are per-process, so you can't write a
script or program which modifies them for the session as a whole (this
is why GRASS has $GISRC).
