Hi GRASS users,

I would like to thank several users who were kind enough to inform me of
some incompatibilities between versions, and even different builds of the
same version of GRASS.  In particular, I'd like to thank Prof. Malcolm
Williamson of Univ. of Arkansas and Ms. Jill Schuler of NRCS of USDA in
responding to my previous question about "<bg> is not a valid parameter". 
The problems have been addressed in our version 1.2.1 release of GRASS-XMI
which was formally released on October 14 (http://www.gpz.com) for

In addition to versions of GRASS mentioned in messages posted earlier, I
did a web search for different versions of GRASS and found two others. 
Here are my questions regarding each version of GRASS.

SAIC's version of GRASS provides capabilities in the vector domain, such as
digitization, measurements, import/export, full topological linking, vector
to raster, contour labeling, linkage to relational database, and many
others. Landsat, SPOT, and NHAP images can be manipulated using the GRASS
image processing capabilities.  It supports Solaris 1.0 for SPARC.

Questions: Does anyone use this version of GRASS on Solaris SPARC 2.x (most
applications built for Solaris 1.x will run on 2.x)?
If someone does, then is this version compatible with CERL's version?
