If you must use a variable to name another variable, use something like
this:
push @{"question_$num"}, $value_label;
The braces allow you to treat the var name like any old string. The quotes
make "question_$num" an interpolated string (just like print
"question_$num";, etc).
I, however, would use a multilayered array of sorts. (look in the Camel Book
under "Data Structures" for more info on that.)
Hope that helps.
