The answer to Alastair Duncan's "Expanding GRASS - Questions" is GRASS-XMI,
a software product that allows you to run GRASS through a user-friendly
X/Motif graphic user interface in the Solaris networking environment.  Here
are the highlights of its most important features.

	- One installation of GRASS-XMI will support the entire organizational
	- Up to six concurrent users can run GRASS-XMI on each computer on the
	- No limit on the number of computers that can run the software
	- One user can run multiple GRASS-XMI sessions on a single CPU, or on
several machines.
	- Multiple users can access the same database at the same time.
	- GRASS-XMI is easy to learn and to use.
	- Input validation occurs before launching a GRASS program.
	- New programs have been added to handle the most tedious user interface
in programs such as r.mask and r.reclass.

Beginning on Sept. 2, 1997, users will be able to download a FREE 30 day
