Justin,
Thanks.  I believe that -duplicates- refers to duplicated observations and
not duplicates within observations between variables.  Am I correct?

Search the help files for 'duplicates'.
This should give you the info you need.

Subject: st: duplicate values of variables
Statalist,
I have a data set in which the unit of analysis is the survey
respondent.
Each respondent was asked to nominate up to ten friends and enter a
unique
id for those friends in the variables friend1-friend10.  What I would
like
to do is run a search through friend1-10 for each respondent to identify
if
the respondent nominated any of the friends more than once by mistake.
If
they did I would like to be able to create a variable(s) which let me
know
the id of the duplicated friend.  
Aid   f1    f2    f3    f4    f5    f6    f7    f8   f9    f10
