Subject   st: create unique variables
Date   Fri, 04 Feb 2005 10:13:10 +0100

I have a dataset with the following variables:

last name
first name
date of birth

Since this dataset contains more than one record for individual, I would create a unique variable for subject (ID).
Could anyone help me in this problem?
Thank in advance
