If you have only one observation per id, you might try
Sort id  * if it makes sense to sort them
Gen idnum=_n


If you have multiple observations per id, you can generalize this easily

Subject: st: Individual IDs with non-numeric characters

Dear all:
 
The individual IDs in my dataset are in the string format. I currently
use -destring- to make them numeric. But, unfortunately, some individual
IDs have non-numeric characters. As a result, -destring- with the
-force- option deletes all these individuals automatically. 
 
Given that I want to sort all the observations, is it possible to keep
these individuals with non-numeric IDs?
 
Any suggestion will be greatly appreciated,
Ben
