Sophie,
The easiest way to work with these might be to leave them as strings and use
substr function (-help substr- for more info) to pull out the answers from
each position.
One thing that will be important to consider is what happens when a question
isn't answered. Your example only contains 10 places, which I assume is
because it's an artificial example and not because answers to 3 questions
are missing. However if missing questions are represented with a zero you'll
definitely want to work with the original string variables rather than using
destring to avoid losing leading zeros.

Subject: st: break string into multiple variables
Dear all,
I've got a number of string variables which contain answers for up to
13 questions within the broad variable category, which when destrung are
listed as one single numeric, e.g. 2222112222 (1 is yes, 2 is no).
I need to create separate variables for each question 1-13.
I haven't been able to find any example code for this on any of the stata
documentation or FAQ. Any advice would be much appreciated.
Many thanks,
Sophie
