Where is S-Plus?

No, sorry, S-PLUS is not free.  Included below is info about it.

As an aside: In the past someone in the GRASS community created the GRASS
"s.menu" commands which facilitated interaction between S-PLUS (or S?) and 
GRASS.  But I believe it was based on a much older version of S-PLUS and would
not work with the current version of S-PLUS.  I really don't know much at all
about s.menu, maybe it has been updated (the info I have is from 1991)?
