This was set by Knuth, and I guess many people know it, but new 
command writers often encounter it, so it's clearly not advertised

I've been following this thread a little, and although I understood

been thinking that you might want to do this with the datatool 
package, which would allow you to keep your question in an Excel file 
and access the questions that way.
