I just wrote some code for this for someone else, so it's fresh on the
brain. 


/* assumes nacimi is numeric and of fixed length */
gen nacimi-1  = real(substr(string(nacimi),1,4))
gen nacimi-2  = real(substr(string(nacimi),-4,4))

-dan

Dear Statalisters,

I have a numerical variable in my data, its name is “nacimi”
I would like to separate the last four digits for to have two variables. For

example:

I have 


   nacimi       
   01041974          
   01051973          
   07041975          
   08061972          

I´d like:

nacimi-1      nacimi-2
0104           1974
0105           1973
0704           1975
0806           1972


Thanks in advance!
