Mike just answerd your question. All I want to add is that if you store
this variable id as a numeric variable you won't store 18 digits, but 7
(the default) or 16 (if you specified that that variable is to be
stored as a double), see -help data types-. If you want to store all 18
digits you will have to make it a string. You can read more on this
issue here: http://www.ats.ucla.edu/stat/Stata/faq/longid.htm

Hope this helps,
Maarten
