The problem is that William Whitaker's Words program returns an error when I 
try to call it with this setup, in Windows 10.  I have a Latin text in a 
buffer. I put the cursor on a Latin word, and strike F12.  The elisp function 
calls the latin.bat bath file, which calls the words latin dictionary program.  
I think something is wrong either with my elisp function or my batch file.

The following error is displayed:

=>Raised END_ERROR, although in STANDARD_INPUT
^Z is inappropriate keyboard input, WORDS should be terminated with a blank line
Giving up!

In .emacs file:

(defun whitaker-lookup ()
"Lookup Latin word at point in Whitaker's words"
(interactive )
(shell-command (concat "C:\latin " (thing-at-point 'word))))
;;C:\latin is a batch file
(global-set-key (kbd "<f12>") 'whitaker-lookup)

Here is the batch file, latin.bat

cd c:\WORDS

The same error occurs if I issue these commands:

m-x shell-command

However, if I go into the shell mode buffer I can make things work:


c:\> cd c:\words
c:\words> words
;;calls the words program with no error
c:\words> latin
;; calls the batch file which calls the words program, successfully.
