If you want filePro to restart the user program, you'll need to CLOSE it 
from within filePro.

     user xxx = /bin/test_script
     aa = xxx
     close xxx
     mesgbox aa

Or, better yet, have the script loop, and have filePro send it something 
every time you want to read from it:

     Script:

         while read junk
         do
             date
         done

     Processing:

         user xxx = /bin/test_script
         xxx = "" ; aa = xxx
         mesgbox aa
