[ESS] submit region with ess-remote and SAS

[Richard M. Heiberger]

I recommend that you use the batch ESS processes for SAS, rather
than the M-x SAS method.   Both give the power of editing your
.sas file.  The iESS was designed for slow terminals (9600 baud)
and still works for that.  But most people now use ether and much
higher speeds.  What ESS calls batch will feel like interactive to
you.

When you are looking at the documentation, read carefully the
section
   ESS[SAS]-Function keys for batch processing
about the append-to-log and append-to-output options.
