John

The suggestion Yves made is very elegant, provided we are interpreting 
your request correctly and you fully understand what [I presume] he 
intends.

I assume you have an input file comprising question numbers, and comma 
or tab and "true", "false" and "unanswered" statements. In this case you 
simply read in the file (get URL) to a variable and loop through it as 
follows:
   (optionally set itemDelimiter to tab)
   repeat for each item Ans in AnswerList
      add 1 to Scoring[item 2 of Ans]
   end repeat.

The scores are then available in Scoring["true"], Scoring["false"], and 
Scoring["Unanswered"].

if unanswered questions are simply empty of a response then you will 
need to test for that, in which case a switch...case statement which 
increments three variables might be faster than the array (since you are 
doing the testing anyway)

600 questions is not much work for Rev. These approaches will process 
such a list in less than a tenth of a second.

Let us know if your requirement is actually different or anything is not 
clear.

regards
David
