I'm having trouble running SAS remotely on a Unix server using the latest
versions of ESS/Emacs. The following is my process that worked on ESS 5.14
/ Emacs 23.3.1, but stopped working at some point in the versions after
1) Start Xming in the background.
2) Start Emacs.
3) Log in to remote server using M-x ssh (and enter appropriate information)
4) Start SAS from the command line using the following command:
sas -stdio -linesize 80 -noovp -nosyntaxcheck -autoexec autoexec.sas
-display **IP Address Here**
5) In ssh buffer with SAS process running, call M-x ess-remote (and enter
"sas" as language).
6) Open SAS file.
7) In the buffer with SAS file highlight region of code to run and submit
code using command M-x ess-eval-region.
In the current versions of ESS/Emacs, the following happens upon completion
of step 7 above:
a) A new buffer with title *shell* is created.
b) An error is displayed in the mini-buffer: "Spawning child process:
Also, when executing step 5 above, I also get the following message in the
mini buffer: Wrong type argument: stringp nil
In the older versions of ESS/Emacs the code that I highlighted would appear
in the buffer of the remote SAS session and the results of the SAS code
would be displayed below the submitted code. (With this workflow, I could
interact with SAS in much the same way I interact with R.)
Under the newer versions of ESS/Emacs I am also no longer able to enter
commands directly at the "command line" in the remote SAS buffer. When I
hit Enter at the command line, the process in the buffer freezes.
Any thoughts on how to fix?
(I've posted on this before, but there were multiple issues with running
SAS processes at that time, and this particular issue was thought to be
related. But the issue still persists in the latest versions of ESS/Emacs.)
