I have a numeric variable (call it id) that comes with 18 digits

like to create a new variable that extracts from the variable 'id'
starting
from the 10th digits and get 4 digits from here.
E.g. my id is given as: 610102001001010300 and I want to create
'newvar'
which has value of 0010.

Any advice on how to handle this would be much appreciated.
Wouldn't this work? (Untested)
. gen str4 newvar = substr(string(id),10,4)
Hope this helps.
