starting inferior Splus process iESS[S]

[Rich Heiberger]

My first response to you got truncated.  Here is the rest.

The command M-x S is designed for the cygwin shell.  To use ESS
with the DOS shell you need the command M-x S+6-msdos

The M-x S and M-x S+6-msdos work with the S-Plus GUI.  Input lines get sent
to the S-Plus commands window.  Output appears in the S-Plus commands window.

The command M-x Sqpe works with S running inside an emacs buffer.  It
provides a smoother interaction for text-only work and is closer in
feel to using ESS and S-Plus on a Unix machine.  All work appears
inside the *S+6* emacs buffer.  It doesn't provide access to the
wingraph device.
