The following example use an external tool to translate the French comments to English comments. The script sends a command name, the string to be translated and waits for the answer.

   SCRIPT TranslateComment(stat) 
     com :=  stat.COMMENT 
     IF (com!=FALSE) THEN 
       STARTTOOL("/udd/foo/bin/translator") 
       SEND("FrenchToEnglish") 
       SEND(com)
       res := RECV() 
       CLOSETOOL("/udd/foo/bin/translator") 
       INSERTCOMMENT(stat,res) 
     ENDIF
   ENDSCRIPT
