You probably want something like this:

(defun acrobat-close-doc (file)
  "Close <file> in Acrobat, using DDE."
    (set-buffer (get-buffer-create " *ddeclient*"))
    (insert (concat "[DocClose( " file ".pdf )]" ))
    (call-process-region (point-min) (point-max)
                         "ddeclient" t t nil "acroview" "control")
    (if (= 0 (string-to-int (buffer-string))) t nil)))

(defun TeX-run-pdfLaTeX (name command file)
  "Create a process for NAME using COMMAND to format FILE with
  ;;  (acrobat-close-all-docs)
  (acrobat-close-doc file)
  (TeX-run-LaTeX name command file))

The problem with you Lisp code is the way you are calling functions.  In
Lisp you call the function 'foo' with an argument arg1 like this:

  (foo arg1)

So instead of


you should say: (acrobat-close-doc file)

[Contrary to popular belief, there are no redundant parens i Lisp :-)]

*But* I still don't think your version will work.  It's been a while
since I used it, but I think the Acrobat DDE interface will only
let you close a *specific* file if you *opened* it through DDE.  

AUC TeX doesn't open files with DDE, so you can't close them that way.
The only easy work-around I could think of at the time was to close all
files in Acrobat, which *is* possible even though they weren't opened
through DDE.

Hm, my emacs doesn't seem to know that variable :-(

The problem is that there isn't really a DTD for ant build.xml files. 
ALthough I think there now is a target to create one from a build file, 
but I am not sure if it's practical if it's constantly changing.
