Justin,

Definitely a possibility that I didn't think of immediately.  The data set
is rather large so I am hoping for a quicker solution that will loop through
the observations for me.  If nothing else, I believe that the reshape will
do just fine.

Thanks.

Carter

Have you thought about possibly reshaping the data and running a
duplicates list command?

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.

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.
