pause for user input

I am trying to use the following routine within a script on multiple drawings. The reason i am using a script is because I have an excell file with 200 file names i need to open up from different locations. It is easy to concoctanate these files in excell and i do not know how to make it as easy in a LISP... I need the program to pause on the "VIEW" command. when used in the script it does not work. I have tried different bit codes for the cmdactive variable and i cannot get it to work... any ideas???

(DEFUN C:PV1 ()
 (command "-view" "W" "1")
  (while
   (= (getvar 'cmdactive) 1)
    (command pause)
 )
(command "-plot" "y" "model" "RICOH C5000 ENG" "Letter (8.5\" X 11\")" "i" "P" "n" "V" "1" "f" "c" "y" "monochrome.ctb" "y" "a" "n" "y" "y")
)

I may be wrong, but I believe that is not possible to pause a script for user input.

I do not write many scripts, but this is my understanding as well.
