Up to now, I have just assigned them as i=question number in question 
folder, j = variant number in the file. So, for instance, Q22-5 is the 
fifth variant in file 22 in the question folder. But when I enter this 
by hand—so far I haven't been able to write a single Apple script both 
for lack of time and lack of ability. (The programmer's mind is 
something different or at least so I fathom when I listen to my Software 
Engineer son)

No doubt for some idiotic reason I have forgotten, I hadn't realized 
that calc was actually computing so now I will at least read the doc.

I will try all of this in a couple of days and get back to report.
