Where is S-Plus?

Tue May 9 16:49:08 EDT 1995

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)?

Below is a portion of the data sheet for S-PLUS 3.2.  Version 3.3 for Unix
will be available later this month.

                           S-PLUS
          Version 3.2 for Windows and UNIX Systems

 S-Plus incorporates the S language developed at AT&T Bell Labs.
