When you start GRASS you are actually executing a shell and setting
a series of environment variables.  These are stored in your 
home directory in a .grassrc file.  You need to set these environment
variables yourself and export them to make them available to you.
I suggest you look at both the script you invoke when you start 
grass, and the GIS.sh called by that script.  

If you want I wrote a short version called grass.cmd to enable me
to start GRASS non-interactively for use with GRASSLinks - an http
interface to GRASS.  My version includes a separate locking mechanism
to allow 5 users called web to run grass concurrently but with
different mapsets.  If you want you can download and untar the GRASSLinks
code and use the file called grass.cmd, in addition to studying the GIS.sh
of the distributed code.

GRASSLinks code is available by anonymous ftp from
ftp.regis.berkeley.edu/pub/grass/grasslinks.tar.Z

Good luck.
