Hi,
I have a numeric variable (call it id) that comes with 18 digits and I would
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.
I know this can be easily done using the 'substr' command, however, I am
having a problem in converting the 'id' into string variable. It gives me
the following command:
***
tostring id, replace
id cannot be converted reversibly; no replace
***
Any advice on how to handle this would be much appreciated.
Thanks,
Susan
